## How many moles are in 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 present in 40 gram of sodium hydroxide?

Thus 40 grams of NaOH equals **one mole** of NaOH, and a 1 molar solution of NaOH will contain 40 grams of NaOH.

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

= 80 / 40= **2 mol** .

## How many moles of NaOH are in 5g of NaOH?

Moles = mass / molar mass

So, **0.125 moles** are present in 5g of NaOH.

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

=**0.10** (approx.)

## How many moles are in 2 grams of NaOH?

240=**0.05**.

## How many moles are present in 8g of sodium hydroxide?

The answer is **39.99711**.

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

Answer: Number of moles which make up 20 grams of NaOH = (20 grams × 1 Mole)/(40 grams) = **0.5 moles**.

## How many moles are there in 5g of water?

**5/18 moles** for 5 grams of water.
