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

One may also ask, how many moles are in 80g of NaOH? This expression means that 2 moles (or 2 x 40 g = 80 g) of NaOH are dissolved in enough water to make one liter of solution.

## How many moles of NaOH are present in 160 g of NaOH?

Hence, the number of moles of sodium hydroxide contained in 160 g of it is 4 moles.

## How many moles are in NaOH?

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles NaOH, or 39.99711 grams.

## How many moles are in 25g of NaOH?

The answer is 0.025001806380511. We assume you are converting between moles NaOH and gram. You can view more details on each measurement unit: molecular weight of NaOH or grams This compound is also known as Sodium Hydroxide.

## How do I calculate moles?

1. 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.
2. 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.

## What is the mass of 0.5 moles of NaOH?

Answer. Answer: In order to get grams, you’ll have to convert one of the volume units. 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 grams are in 2 moles of MgCl2?

For example magensium chloride has the formula unit MgCl2 , i..e., for every magnesium cation there are two chloride anions in the crystal. Or, we would say that the formula weight of MgCl2 = 95.211 g/mol (i.e., 95.211 g of magnesium chloride has a mole of magnesium cations and 2 moles of chloride anions.
