One mole of any substance weighs about the same as the molecular mass of that substance. Hence, the number of moles of sodium hydroxide contained in 160 g of it is 4 moles.

## How many moles are in 4 grams of NaOH?

=0.10 (approx.)

## What is the mass of 4 moles of NaCl?

The molar mass of sodium chloride is 58.4 g/mol. This means that one mole of NaCl will weigh 58.4. 4 moles of NaCl will weigh 4 times as much. We can…

## What is the mass of 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. g with the right number of significant figures.

## How many moles are in NaOH?

First, the molar mass of NaOH is 39.997 g/mol. Divide the mass by the molar mass and you’ll have the equation: 60 g / 39.997 g/mol. The grams cancel and you are left with 1.50 moles of NaOH.

## What is the molar mass of NaOH?

1 mole of sodium hydroxide has a mass of 40.00 g⋅mol−1 .

## How many grams is 4 moles of sodium chloride?

Approx. 250⋅g of salt.

## How many moles are in 90 g of NaOH?

There are 2.25 moles of NaOH in 90g of NaOH.

## What is the mass of 4 mol of HCl?

Therefore, in the presence of an excess of Cl_{2}, 2.00 mol H_{2} will react completely to give 4.00 mol HCl. = 4.00 mol x 36.46 g mol^{–}^{1} = 146 g.

## What is the mass of 2 mole of NaOH?

Answer: The molar mass of the compound NaOH is 40 g/mol.

## How many grams of NaOH is there in 3 moles of NaOH?

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles NaOH, or 39.99711 grams. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between moles NaOH and gram.

## How do you calculate 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.

## What is one mole of NaOH?

One mole of NaOH has a molar mass of 40.0 g, so 40.0 g of NaOH dissolved in 1 kg of water results in a one-molal NaOH solution. If 20.0 g of NaOH, which is 0.500 mol of NaOH, is dissolved in exactly 1 kg of water, the concentration of the solution is 0.500 m NaOH.

## How do you calculate the number of moles of NaOH?

Calculate the number of moles of NaOH used in reaction 3 by multiplying the volume of NaOH times the molarity (1.000 mol/L).
