Answer: 33.3 moles
Explanation: 67.2 g H2 = 67.2/2.016 = 33.3 moles
7.55 x 6.02 x 10²³ = 4.55 x 10²⁴ atoms
Answer:
d I think there's two answer
Explanation:
or c
The density of hydrogen : ρ = 0.0892 g/L
<h3>Further explanation</h3>
Given
mass of Hydrogen : 0.446 g
Volume = 5 L
Required
The density
Solution
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
The unit of density can be expressed in g/cm³, kg/m³, or g/L
Density formula:

Input the value :
ρ = m : V
ρ = 0.446 g : 5 L
ρ = 0.0892 g/L
It could be Nitrous oxide
