Question

відносна густина газу х за гелием - 8, маса його 24г. обчисліть малярну масу газу та кількість речовини.

Answer 1

1 моль газа занимает объем 22,4 л (н.у)

1,43 г----------0,5 л

х----------------22,4л

х=64 г => М=64г/моль (возможно SO2)

D(H2)=М/М(Н2)=64/2=32

D(возд)=М/М(возд)=64/29=2,2ние:

Answer 2

Relative Density of Gas X and Helium

The relative density of a gas is the ratio of its density to the density of a standard gas, usually air or hydrogen. In this case, the relative density of gas X to helium is given as -8 and the mass of gas X is 24g.

To calculate the molar mass of gas X and the amount of substance, we can use the following steps:

1. Calculate the Molar Mass of Gas X: The molar mass of a substance is the mass of one mole of that substance. It is calculated by adding up the atomic masses of
