Question

How many moles is 34.4 g of Oxygen gas (O2)?

Answer 1

n = 1.075 moles

Step-by-step 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,

`n=(34.4\ g)/(32\ g/mol)\\\\=1.075\ mol`

So, there are 1.075 moles in 34.4 g of Oxygen gas.
