A mixture of `4 g` of hydrogen and `8 g` of helium at (NTP) has a dencity about.

Text Solution

Verified by Experts

The correct Answer is:
`0.12`
Volume occupied by 1 mole of an ideal gas at NTP = 24.8 lt. and total number of moles are ` (4/2 + 8/4)= 4`
`rArr " Density "= ((4+8)xx10^(-3)kg)/((24.8 xx 4)xx10^(-3) m^2) = 3/(24.8) kg//m^3 = 0.12 kg //m^3`
