Answer:
Explanation:
Given,
The density of Helium is
We need to find the density in Dg/μm
We know that,
1 g = 10 dg
1 cm³ = 10¹² μm³
So,
So, the density of Helium is equal to .

Balanced reaction:
According to balanced reaction-
8 moles of are produced from 2 moles of
So, 8.70 moles of are produced from
moles of
or 2.175 moles of
Molar mass of = 58.12 g/mol
So, mass of required =
= 126.4 g
Hence 126.4 g of are required
