## How many moles are in 1g of NaOH?

Determining the Molar Mass of a Compound

In a compound of NaOH, the molar mass of Na alone is 23 g/mol, the molar mass of O is 16 g/mol, and H is 1 g/mol. What is the molar mass of NaOH? The molar mass of the compound NaOH is 40 g/mol.

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

So 8.0 grams of helium divided by 4.0 grams per mole gives us 2.0 moles of helium.

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

Hence, 0.100 moles are present in 4 grams of NaOH.

## How many moles are in 1 mole of NaOH?

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 grams of NaOH are in 3 moles of NaOH?

A 3.0 M solution of NaOH has 3.0 moles of NaOH per liter of solution. There are 0.25 L of solution (250mL⋅1L1000mL) , so there are 0.25L⋅3.0mol/L=0.75mol of NaOH. The molar mass of NaOH is 40.0 g/mol, so there are 0.75mol⋅40.0g/mol=30g of NaOH, 30.

## How do I calculate moles?

How to find moles?

1. Measure the weight of your substance.
2. Use a periodic table to find its atomic or molecular mass.
3. Divide the weight by the atomic or molecular mass.
4. Check your results with Omni Calculator.

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

= 80 / 40= 2 mol .

## How many grams are in 12 moles of he?

Just under 50⋅g .

## How many grams is 10 moles of water?

So, 10 mole of water will weigh (18×10) = 180g.

## How many moles are present in 12g of sodium hydroxide?

The answer is 39.99711. We assume you are converting between grams NaOH and mole.

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

100/58.44=1.71! Hope this helped.

## How many grams is 0.5 moles of NaOH?

I’ll do it this way: (0.5 moles/liter NaOH) * (0.2 liter end volume) * (40.0 g/mole) = amount to weigh out Now the units cancel, except for grams, giving 4.00 g.

## 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.
