## How many moles are in sodium hydroxide?

Mole is a widely used unit for calculating the amount of matter of a substance. One mole of any substance weighs about the same as the molecular mass of that substance. Hence, the number of moles of sodium hydroxide contained in 160 g of it is **4 moles**.

## How many moles are in 40g 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 in 30g of NaOH?

30g sample= **0.75 mole**.

## How many molecule of NaOH are there in 80 grams of sample?

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 .

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

=**0.10** (approx.)

## 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 formula for moles to grams?

Moles to grams example problem

Solution: Find out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). The molar mass of KClO3 is 122.548 g/mol. **Multiply the given number of moles** (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.

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

Number of moles of NaOH = 20gm40gm/mol = **0.5 moles**. Therefore, 20 gm NaOH dissolved in 500 ml of solution has 1M of molarity.

## How many moles are in 8 grams of NaOH?

The answer is **39.99711**.
