Contents

## How many moles are equal to 15 grams of oxygen?

So the answer would be (23.584-22.347)grams divided by 16.000 g/mol, or 7.7313×10^-2 moles O2.

## How do you find moles of oxygen?

Calculate the number of oxygen atoms in 1 mole of O2. Solution — 1 molecule of O2 = 2 oxygen atoms So, 1 mole of O2 = 2 mole oxygen atoms = 2 × 6.022 × 1023 = 12.044 ×1023 oxygen atoms.

## How many grams are in 10 moles of oxygen?

mass = 320 grams….

## How many grams are in 4 moles of oxygen?

4 moles of oxygen gas would be equivalent to 4 moles x 32 g/mole = 128 g. Thus, 4 moles of oxygen gas (O2) would have a mass of 128 g.

## How many moles are in 1 kg of oxygen?

so,62.5 moles of oxygen have (6.022×10^23×62.5) molecules. Hence 1 kg of oxygen has (376.38×10^23) molecules.

## How much would 3.000 moles of oxygen weigh?

1 Answer. 3 moles of Oxygen atoms weigh 48.00 grams.

## How many moles are there in 32 grams of oxygen?

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

## What is the formula for moles to grams?

In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass.
