How many molecules are present in N2?

## How many moles of dioxygen are present in 128g of oxygen?

The number of mole present in 128 g of oxygen is 16.

## What is the number of molecules in 64 gram of oxygen?

so,your answer is 12.04×10^23 molecules.

## How many moles of dioxygen are present in 96g of Dioxygen?

Therefore, according to the question, it is given that, weight of ${O_2}$ is 96 grams and is contained in the volume of vessel 2 liters. Hence, the number of moles is 3.

## How many moles are 24g of oxygen?

1 mole of oxygen is 6.02 x 1023 atoms of oxygen 1 amu = 1.661 x 10-24gWhat is the molar mass (g/mole) ofoxygen? Molar mass (in grams) is always equal to the atomic weight of the atom!

## How many moles of dioxygen are present in 16g of Dioxygen?

molar mass of oxygen is 16 grams, it means that 1 mole oxygen weighs 16 grams. therefore 64 gram oxygen = 64/16 = 4 mole oxygen.

## How many atoms are present in 64 amu of oxygen?

Answer: There are 4 atoms present in 64 amu of oxygen. Explanation: We know that, one oxygen atom has atomic mass 16 u.
