Question

vapour density of hydrogen is 1, as compared to air being_______​

Answer 1

Answer:

The ratio of the mass of a given volume of one gas to the mass of an equal volume of another gas, typically hydrogen, at the same temperature and pressure. ... The lower the density of the gas the faster it rises. If the value of the RVD is greater than 1 then the gas is more dense than air and will sink...

Answer 2

ratio of the mass of the given volume of one gas to the mass of an equal volume of an another gas typically hydrogen at the same temperature and pressure. the lower density of the gas the faster it Rises. if the value of the RVD is greater than 1 then the gas is more dense then air and it will sink
