# Best answer: How many grams are in 1 mole of sodium hydroxide?

Contents

## How do you convert 1 mole to grams?

In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass.

## How many grams are in 2 moles of NaOH?

How many grams are in 2 moles of sodium hydroxide? 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 do you find the moles of NaOH?

Step 1: Calculate the amount of sodium hydroxide in moles

1. Amount of solute in mol = concentration in mol/dm 3 × volume in dm 3
2. Amount of sodium hydroxide = 0.100 × 0.0250.
3. = 0.00250 mol.
4. The balanced equation is: NaOH(aq) + HCl(aq) → NaCl(aq) + H 2O(l)
5. So the mole ratio NaOH:HCl is 1:1.

## How many grams of NaOH do I need?

The molar mass of NaOH is 40 g/mol. Thus, the mass of NaOH which will be required to prepare 500 mL of 0.1M solution is 2.0 g.

## Why do we convert moles to grams?

When substances react, they do so in simple ratios of moles. … Balances DO NOT give readings in moles. So the problem is that, when we compare amounts of one substance to another using moles, we must convert from grams, since this is the information we get from balances.

## Are moles equal to grams?

The mass of 1 mole of a substance is equal to its relative atomic or molecular mass in grams.

## 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.
