## 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**

- Amount of solute in mol = concentration in mol/dm
^{3}× volume in dm^{3} - Amount of sodium hydroxide = 0.100 × 0.0250.
- = 0.00250 mol.
- The balanced equation is: NaOH(aq) + HCl(aq) → NaCl(aq) + H
_{2}O(l) - 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.

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

The answer is **39.99711**.
