A gaseous hydrocarbon collected over water at a temperature of 21°C and barometric pressure of 753 torr occupied a volume of 48.1 mL. The hydrocarbon in this volume weighs 0.1133 g. Calculate the molar mass of the hydrocarbon. The vapor pressure of water at 21°C is 18.7 torr. Using experimental data obtained from the question above, calculate the volume of the hydrocarbon at standard temperature and pressure (STP). Account for the vapor pressure of water.

Crystallography

Crystallography is the category of science that focuses on the atomic and molecular arrangements with their bonding constituting the crystal structure. It is derived experimentally and originated in the year 1912. It is a combination of two words; those are crystal, meaning a cold drop, and graph, meaning writing.
