To find the volume of 2.5 mol of hydrogen gas, we can use the Ideal Gas Law equation: PV = nRT. We are given the pressure (152 kPa), temperature (-20.0 degrees Celsius which is equivalent to 253.15 K), and the number of moles (2.5 mol). We can rearrange the equation to solve for volume (V), V = (nRT)/P. Plugging in the values, V = (2.5 mol x 8.314 J/mol·K x 253.15 K) / 152 kPa = 3.51 L. Therefore, 2.5 mol of hydrogen gas will occupy a volume of 3.51 liters at -20.0 degrees Celsius and 152 kPa.

A piece of foam padding has a volume of 1500 cm3 and a mass of 200 g What is the density of the foam?
Density = mass/volume so in this case 200/1500 = 0.13 g/cm3
The pressure acting on 50 cubic meters of gas is raised from 200 kPa to 400 kPa The temperature remains constant What is the new volume?
800mm Hg Pressure and Volume are inversely proportional... thus is volume is halved (400ml -> 200ml) then pressure would double (400 mmHg -> 800 mmHg)
If something has a mass of 4000grams and a volume of 20ml what is the density?
It has a density of 200 g/mL

About how many kilograms of air occupy a classroom that has a 200-square meter floor area and a 4-m-high ceiling?
Density of air at the sea level is about 1.2 kg/m3. Volume of the classroom would be 200 * 4 = 800 m3, and the air mass equals volume times density, which gives: m = 960 kg.
