# Best answer: How many moles are in 20 grams of NaOH?

Contents

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

## How many moles are in 20 grams?

There are 5.00 moles He in 20.0 g He.

## How many moles are there in 20 grams of sodium?

So, the molar mass of NaCl = 35.5 gmol−1 +23 gmol−1= 58.5 gmol−1. Now, we have to use the following formula to calculate the number of moles of NaCl. The mass of NaCl is given as 20g. So, the number of moles of NaCl present in 20 g of NaCl is 0.342 mol.

## How many moles are in NaOH?

First, the molar mass of NaOH is 39.997 g/mol. Divide the mass by the molar mass and you’ll have the equation: 60 g / 39.997 g/mol. The grams cancel and you are left with 1.50 moles of NaOH.

## How many grams NaOH in a mole?

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

## What is the molar mass of NaOH?
