Avogadro's law and molar volume of gases

Which volume of oxygen is required to react fully with 40.0 cm3 of butane to ensure complete combustion? $\ce{2C4H10(g) + 13O2(g) -> 8CO2(g) + 10H2O(g)}$ A. 520 cm3 B. 260 cm3 C. 130 cm3 D. 40.0 cm3

What volume of propane gas, in $\mathrm{cm^3}$, must be burned completely in oxygen to give 90 $\mathrm{cm^3}$ of carbon dioxide, all volumes being measured at the same temperature and pressure? $\ce{C3H8(g) + 5O2(g) -> 3CO2(g) + 4H2O(g)}$ A. 18 B. 30 C. 90 D.…

90.0 $\mathrm{cm^3}$ of buta-1,3-diene and 150.0 $\mathrm{cm^3}$ of hydrogen are mixed in a container at 450 K and 101 kPa and react to form butane only. Determine the maximum volume of butane that can be formed, measured at the same temperature and pressure.

30 $\mathrm{cm^3}$ of butane was completely burned in 250 $\mathrm{cm^3}$ of oxygen according to the following equation. $\ce{2C4H10(g) + 13O2(g) -> 8CO2(g) + 10H2O(l)}$ What volume of oxygen remains unreacted, measured at the original conditions? A. 55…

0.30 $\mathrm{dm^3}$ of nitrogen is mixed with 0.60 $\mathrm{dm^3}$ of hydrogen and the mixture reacts as completely as possible. All gas volumes are measured at the same temperature and pressure. $\ce{N2(g) + 3H2(g) -> 2NH3(g)}$ What volume of ammonia, in…

Equal volumes of the gases $\ce{Q2}$ and $\ce{R2}$ are mixed in a sealed container and react until one of them is used up, forming the gas $\ce{QR2}$. The volume of $\ce{QR2}$ formed, measured under the same conditions, is 50 $\mathrm{cm^3}$.…

$10.0\ \mathrm{cm^3}$ of a gaseous hydrocarbon, $\ce{C_xH_y}$, is burned completely in exactly the required volume of oxygen. The gaseous products occupy $70.0\ \mathrm{cm^3}$. This falls to $30.0\ \mathrm{cm^3}$ once the water vapour present condenses, with…
