## How many moles are in 10 grams of sodium hydroxide?

The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide. The SI base unit for amount of substance is the mole.

## How do I find molar mass?

The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol). The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms.

## What’s the mass of Fe?

55.845 u

## How many atoms are in a mole?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

## How much does it cost for 1 gram of iron?

## How many atoms are in FE?

3.77mol Fe ×6.022×1023atoms Fe1mol Fe =2.27×1024 atoms Fe rounded to three significant figures.

## How many moles are in 1 gram of sulfur?

The SI base unit for amount of substance is the mole. 1 grams Sulfur is equal to 0.031186652112896 mole.

## How do I calculate moles?

- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.

## How many moles of Fe atoms are in 100g?

Conclusion: 1.79 moles are there in 100g of iron.
