Calculate the density in g/ml of 2.0 L of gasoline that weighs 1.32 kg
Answers
Answer: 0.66 g/mL
Explanation: The formula for density is d= m/v where m=mass and v=volume.
The mass was given in the problem, m= 1.32kg
The volume was also given in the problem, v= 2.0L
d= m/v ---> d= 1.32kg/2.0L ---> d=0.66kg/L
The problem calls for the answer to be written in g/mL, so we must convert the units. 1 kg contains 1000g and 1 L contains 1000 mL.
1000g/1000mL = 1 so the units change but the 0.66 does not. Therefore, your answer is 0.66g/mL (Two significant figures because 2.0 only has 2 significant figures).

There is a double bond between the carbon atoms and a lone pair on oxygen.
What is Lewis structure?The term Lewis structure has to do with the structure that shows the arrangement of atoms in a compound. It is normal that the structure would be composed of the symbols of the elements and the bonds that they form as dots or sometimes as a single line to show shared electrons.
Now we can see that the compound C2H2O is a compound that contains a double bond between the carbon atoms. There is a lone pair of electron that resides on the oxygen atom. The structure of this compound is shown in the image attached.

How many moles (of molecules or formula units) are in each sample?
Express your answer in moles to three significant figures.
1) 18.0 g NO2
2) 1.35 kg CO2
3) 46.1 g KNO3
4) 191.8 kg Na2SO4
Answers
The number of moles in each sample will be 0.391 moles, 30.7 moles, 0.456 moles, and 1350 moles
What is the number of moles?The number of moles of a substance is the ratio of the mass of the substance to the molar mass.
In other words; mole = mass/molar mass.
Thus:
moles of 18.0 g [tex]NO_2[/tex] = 18.0/46= 0.391 moles
moles of 1.35 kg [tex]CO_2[/tex] = 1350/44= 30.7 moles
moles of 46.1 g [tex]KNO_3[/tex] = 46.1/101.1= 0.456 moles
moles of 191.8 kg [tex]Na_2SO_4[/tex] = 191800/142= 1350 moles

What is concentration of N2O5 in the following first order reaction in which the rate is 2.4*10^-5 mole/L and rate constant is 3 * 10 ^ - 5 * S ^ - 1 ?
Answers
0.8mole/L is concentration of N2O5.
As the reaction is first order ,
so the order with respect to N2O5 is 1.
general,
Rate of equation is written as
rate = k [N2O5]^1
k is the rate constant = 3 * 10 ^ - 5 * S ^ - 1
rate = 2.4*10^-5 mole/L
N2O5 is concentration term
2.4*10^-5 mole/L = 3 * 10 ^ - 5 * S ^ - 1 [ N2O5]
N2O5 = [0.8 mole/L]

Answers
The number of mole of tin (Sn) that you have is 0.058 mole
Avogadro's hypothesis6.02×10²³ atoms = 1 mole of tin (Sn)
With the above information, we can obtain the number of mole ot tin. Details below
How to determine the mole of tin that contains 3.5×10²² atomsWe can obtain the number of mole of tin as follow:
6.02×10²³ atoms = 1 mole of tin (Sn)
Therefore,
3.5×10²² atoms = (3.5×10²² atoms × 1 mole) / 6.02×10²³ atoms
3.5×10²² atoms = 0.058 mole of tin (Sn)

The amount of heat absorbed by the calorimeter in this reaction must be determined before you can calculate the enthalpy of the reaction that occurs inside of it.
To do this, suppose that you measure exactly 43.5 mL of cool water at 22.0°C and
place it into a calorimeter. Then you add 21.0 mL of warm water (initial temperature
of 37.0°C) to the calorimeter. The final temperature of the entire system is 25.5°C.
Compute the heat capacity of the calorimeter in J K–1 assuming that no heat leaks
into or out of the calorimeter.
Answers
The heat capacity of the calorimeter is 16.8 J/K.
What is the heat capacity of the calorimeter?Now we know that the calorimeter is a device from which there is no heat loss or gain. In this case, the heat lost by the hot water is equal to the heat gained by the calorimeter.
Thus;
cwθ = ccθ
Where;
cc= heat capacity of the calorimeter
cw = heat capacity of water
θ == temperature change
Hence;
4.2 * (37 - 25) = cc (25 - 22)
cc = 4.2 * (37 - 25)/(25 - 22)
cc = 16.8 J/K

O Decreasing the mass of the airplane will result in the airplane accelerating less.
O Increasing the acceleration of the airplane causes the engine to provide less force.
O Decreasing the mass of the airplane will result in the airplane accelerating more.
Answers
If the engines in both airplanes are at the same weight, the engines in both airplanes would still have the same mass because mass is constant everywhere.
What is mass?Mass can be experimentally defined as a measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied.
In the question, the same type of engine is placed in two different air-planes of which the first airplane is twice as heavy as the second.
We can then conclude that the correct statement about the mass of the airplane and its acceleration, assuming a constant net force is that Increasing the acceleration of the air-plane causes the engine to provide more force.
