The molal concentration of the solution is 5.38 M.
The molal concentration of sulphuric acid = 6.80 m
The density of the solution = 1.318 g/ml
Mass of the sulphuric acid in the solution is,
[tex] = 6.80 \times 9.80[/tex]
[tex] =666.4 \: g[/tex]
The mass of sulphuric acid present in the solution is 666.4 g.
Let the mass of the solvent in which sulphuric acid is dissolved be 1000 grams.
So the total mass of the solution is,
= Mass of solvent + Mass of sulphuric acid
[tex] = 666.4 \: + \: 1000[/tex]
[tex] = 1666.4 \: g[/tex]
The total volume of the solution is,
[tex] = \frac{1666.4 \times 1}{1.318 \times 1000} [/tex]
[tex] = 1.264 \: L[/tex]
The volume of the solution is 1.264 liters.
The molal concentration of this solution is,

You want to know how much total energy is required to operate a 100-watt light bulb. do you need any more information?
Yes; you need to know how long the light bulb is on.
How much electricity does a light bulb use?Because of this, lower wattage bulbs are sometimes referred to as "equivalent to 60W"; nevertheless, what is equal is brightness, not energy consumption.
Converting wattage to kilowatts is the best way to determine how much energy your lightbulb consumes. Thus, 0.1 kW would be needed per hour for a 100W light bulb.
Incandescent (up to 100W) and halogen (up to 120W) light bulbs with higher energy consumption are being phased out. You may get ornamental exposed carbon filament light bulbs, which are normally 40–60W, if you still have any of them operating in your house.

A 22.2 g sample of gold with a density of 0.01932 kg/cm3 will occupy a volume of 1.1491 cm3.
Density, denoted by ρ, of a substance is its mass per unit volume. It shows the ratio between a substance mass and the volume it occupies. To solve for density, the formula is given by
ρ = mass / volume
Given a substance density, we can compute for its mass or volume using the same formula and vice versa.
But before inputting the values, convert the mass from g to kg to match the unit of density. (1 kg = 1000g)
mass = 22.2 g = 22.2 / 1000 = 0.0222 kg
To compute for the volume a sample of gold occupies,
volume = mass / ρ
where mass = 22.2 g = 0.0222 kg
