In the reaction CH4 + 2 O2 ? CO2 + 2 H2O, what volume of oxygen (dm3) at RTP is required to burn 1.00 dm3 of methane at RTP?
When 0.500 mol of hydrogen gas is produced at RTP, what volume in dm3 and in cm3 does it have?
A 250 cm3 gas syringe contains nitrogen at RTP. How many molecules of nitrogen are present? (Avogadro constant = 6.02 × 10^23 mol-1; 24 dm3 per mole at RTP.)
A student collects 15.0 cm3 of oxygen gas at RTP. What mass (in grams) of oxygen (O2) has been collected? (Ar O = 16)
Ammonia decomposes to nitrogen and hydrogen: 2 NH3(g) ? N2(g) + 3 H2(g). If 48.0 dm3 of NH3 at RTP decomposes completely, what total volume of gas (dm3) at RTP will be present after decomposition?
A flask contains 0.750 mol of oxygen. If the gas is compressed isothermally to half its original volume at RTP, how many moles change?
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 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.)
Which expression correctly gives moles of gas n from volume V at RTP using molar volume Vm?
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?
A container holds 48.0 dm3 of oxygen gas at room temperature and pressure (RTP, 24 dm3 per mole). How many moles of oxygen are present?
