The ratio of the mass of a certain volume of gas to the mass of an equal volume of hydrogen under the same conditions of temperature and pressure is known as_______

Equal volumes of all gases under the same conditions of temperature and pressure contain equal number of

Equal volumes of all gases under similar conditions of temperature and pressure contain equal number of atoms.

In a Regnault's experiment, the mass of a definite volume of a gas was found to be 4.6420 g, whereas the mass of the same volume of hydrogen at the same temperature and pressure was found to be 0.2902 g. Calculate the vapour density and molecular mass of the gas.

when gases react together their reacting volumes bear a simple ratio to each other under the same conditions of temperature and pressure . Who proposed this law ?

A vessel contains X number of molecule of hydrogen gas at a certain temperature and pressure. How many molecules of oxygen will be present in a vessel of same volume under the same conditions of temperature and pressure? Name the law to justify your answer.

One volume of a gaseous compound containing carbon, hydrogen, and oxygen was burnt in the presence of 2 volumes of oxygen. The resultant gases contained 2 volumes of carbon dixoide and 2 volumes of steam. Find the molecular formula of the compound, if all the volume were measured under the same conditions of temperature and pressure.

Solve A vessel contains X number of molecules of hydrogen gas at a certain temperature and pressure. How many molecules of nitrogen gas would be present in the same vessel under the same conditions of temperature and pressure ?

A gas cylinder full of hydrogen gas contains 6 g of this gas. The same cylinder can hold 102 g of a gas X under the same conditions of temperature and pressure. Calculate the vapour density of the gas X

It is desired to fill a cylinder of 1 L capacity at 82 atm and 27^(@)C with hydrogen. What will be the volume of hydrogen under standard conditions of temperature and pressure?

A gas cylinder can hold 1 kg of hydrogen at room temperature and pressure : If the number of molecules of hydrogen in the cylinder is X, calculate the number of CO_2 molecules in the cylinder under the same conditions of temperature and pressure.
