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.
