## 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**.

## What is the mass of 4.00 moles of oxygen gas?

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 of oxygen is present in 640 grams?

therefore 64 gram oxygen = 64/16 = **4 mole oxygen**. 1 mole of any element contains 6.022 * 10^23 atoms in it.

## How many moles are in 32g 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.
