Chapter 2-DF8

Question 1

What is Avogadro’s law?

Answer 1

Equal volumes of different gases at the same pressure and temperature will contain equal numbers of particles

Question 2

How do you calculate the volume of a gas from a given mass?

Answer 2

Calculate the amount in moles from the mass - Moles=mass/molar mass
Calculate the volume at r.t.p
volume x moles

Question 3

How do you calculate the mass of a gas from a given volume?

Answer 3

Calculate the amount in moles-moles=volume/molar mass
Calculate the mass- mass=moles x molar mass

Question 4

What is the ideal gas equation?

Answer 4

pV = nRT
p=pressure(Pa), V=volume(m3), n=no. of moles, R=gas constant(8.31JK-1 mol-1), T=temperature(K)
