240=0.05.

## How many moles are in NaOH?

Since the molar mass of NaOH is 40 g/mol, we can divide the 90 g of NaOH by the molar mass (40 g/mol) to find the moles of NaOH. This the same as multiplying by the reciprocal of 40 g/mol. If the equation is arranged correctly, the mass units (g) cancel out and leave moles as the unit.

## What is the number of moles in 20g of sodium hydroxide?

▶Number of moles in 20g of NaOH = 2.

=0.10 (approx.)

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

Moles = mass / molar mass

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

## What is 1M NaOH?

of moles of solute / 1 liter . * one moles of sodium hydroxide = 40 gm of sodium hydroxide. … Weigh 39.9 gm of NaOH pellets & dissolve them in one liter of water, what you will be having now is 1M NaOH solution.

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

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

## 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.
