# How many moles are there in 80 grams of sodium hydroxide?

Contents

## How many moles are in 80 grams of NaOH?

= 80 / 40= 2 mol .

## How many molecules are present in 80 grams of sodium hydroxide?

In 80 grams there will be 2 molecules of NaOH, so mass of Sodium would be 23 x 2 = 46g.

## 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 .

=0.10 (approx.)

## 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 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).

## What is the mass of 0.5 mole of sodium hydroxide?

However, in expressing the concentration as M (molarity) the volume of the solution is also taken into account. Thus, 0.5 mole of NaOH represents simply 20 g of the base while 0.5 M means 20 g of the base or NaOH dissolved per litre of the solution.

## How many grams are in 1.5 moles of water?

Conclusion: Thus it can be inferred that the mass of 1.5 moles of water is 27g.
