Question

calculate the no. of moles in 32 g of oxygen gas

Answer 1

molar mass of oxygen gas =2*16=32
$no \: of \: moles \: of \: oxygen \: gas = \frac{given \: mass}{molar \: mass} = \frac{32}{32} = 1$

Answer 2

The no. of moles in 32 g of oxygen gas is 1.

Explanation:

The number of moles present in 32 gram of oxygen needs to be found out.

As we know  the molar mass of the gas or in this case oxygen is 2$\times$ 16 which gives 32.

The weight of the amount of oxygen of which the number of moles has to be calculated is given as 32.

And we know that When the given mass is divided by the molar mass of the gas.

We will get the number of moles present in that gas so here it is $\frac{32}{32}$=1.

we get the answer as 1. So the number of moles present in 32 gram of oxygen is 1.
