Question

find mole of 26 g of oxygen

Answer 1

The answer is 1.625

Answer 2

Hey,
Thanks for asking this question.

We need to find the mole of 26 gram of Oxygen gas.

We already know that atomic mass of Oxygen (O) is 16 amu.

So molar mass of O2 = 16×2 gram
So molar mass of O2 = 32 gram

It means 32 gram of Oxygen gas = 1 mole

=> 1 gram of Oxygen gas = 1/32 mole
=> 26 gram of Oxygen gas = 26/32 mole
●●●=> 26 gram of Oxygen gas (O2) = 0.8125 mole

Similiarly if we have to find mole of 26 gram O,
then number of mole = 26÷16 = 1.625 mole.


■Hope my answer helps.
