Use Of Amount Of Substance In Relation To Volumes Of Gases (chemistry Only) (ht Only) (GCSE Chemistry)

A sample of carbon monoxide (CO) gas occupies 10.0 cm3 at RTP. If completely oxidised to CO2, what volume of CO2 (cm3) at RTP will be produced?

A reaction at RTP yields 0.0200 mol of gas. What is the corresponding volume in cm3?

When 0.500 mol of hydrogen gas is produced at RTP, what volume in dm3 and in cm3 does it have?

A gas occupies 600 cm3 at RTP. Express this volume in moles.

A reaction produces 30.0 cm3 of a gas at RTP over 10.0 seconds. What is the rate in cm3 s-1 and in mol s-1?

If 0.0600 mol of gas at RTP occupies 1.44 dm3, what molar volume did the student effectively use?

1.20 g of hydrogen gas (H2) is collected at RTP (24 dm3 per mole). What volume does this hydrogen occupy? (Ar: H = 1)

At RTP, 2.4 g of methane (CH4, Mr = 16) is burned producing CO2. What volume of CO2 (dm3) at RTP is formed, assuming complete combustion?

A student measures 600 cm3 of hydrogen at RTP produced from reacting magnesium with acid. How many molecules of hydrogen is this? (Use 24 dm3 = 24 000 cm3 per mole and Avogadro 6.02×10^23.)

Hydrogen gas is collected over water; the collected gas volume is 50.0 cm3 at RTP but water vapour contributes 2.0 cm3. What is the volume of dry hydrogen at RTP and the number of moles?

A gas reaction at RTP gave 36.0 dm3 of product gas. If that product corresponds to 1.50 mol, what molar volume (dm3 mol-1) was used by the student?
