= 80 / 40= 2 mol .

## What is the number of moles in 80 grams of water?

Solution – Chemical formula of water is H2O. 1 mole of water weighs 18 gram. Therefore, 80 gram of water is equal to 4.4 moles.

## How many moles are there in 60 gram of sodium hydroxide?

Answer : The number of moles in 60 g of NaOH is 1.5 moles.

## How many moles are in NaOH?

The molar mass of the compound NaOH is 40 g/mol.

## How many moles are in 1 gram of sodium hydroxide?

The molar mass tells you the mass of exactly one mole of a given substance. In this case, sodium hydroxide has a molar mass of 39.997 g mol−1 , which implies that one mole of sodium hydroxide has a mass of 39.997 g .

## How many moles are there in 80 grams of oxygen?

Gram atomic mass of Oxygen is 16 g. Therefore, 80 g of Oxygen will contain = 80/ 16 = 5 moles.

## How many gram moles are contained in 80 gram of oxygen?

1 mole = 6.022 x 1023 particles. Calculate the number of moles present in 80 grams of Oxygen. = 2.5 moles Ans.

## How many moles are there in 40g of NaOH?

1 mole of NaOH =40g by mass /40g by molar mass. Which is =1. 1 mole of NaOH contains 7.53*10^23 atoms.

## How many moles are there in 100 grams of NaOH?

100/58.44=1.71!

## How many moles are in 4.75 g of sodium hydroxide?

4.75 g of NaOH (1.19 x 101 mol NaOH) Answer: The molar mass of NaOH was solve in section A to be 40 g/mol.

## How many moles are in 20g of NaOH?

20 gr of NaOH correspond to 0.5 moles which are contained in 0.5 liter of solution.

## How do I calculate moles?

How to find moles?

- Measure the weight of your substance.

- Check your results with Omni Calculator.

## What is the mole formula?

Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).
