Answer:
n = 1.075 moles
Explanation:
Given that,
Mass of oxygen = 34.4 gram
The molar mass of oxygen gas = 32 g/mol
We need to find the number of moles of oxygen. We know that,
No. of moles = given mass/molar mass
So,
[tex]n=\dfrac{34.4\ g}{32\ g/mol}\\\\=1.075\ mol[/tex]
So, there are 1.075 moles in 34.4 g of Oxygen gas.
