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

= 80 / 40= **2 mol** .

## How many moles are in NaOH?

Determining the Molar Mass of a Compound

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

## How many molecule of NaOH are there in 80 grams of sample?

In 80 grams there will be **2 molecules** of NaOH, so mass of Sodium would be 23 x 2 = 46g.

## How many moles of NaOH is 60g of NaOH?

Answer : The number of moles in 60 g of NaOH is **1.5 moles**.

## 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.

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

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 moles are in 4.75 g of sodium hydroxide?

4.75 g of NaOH (1.19 x **101 mol NaOH**) Answer: The molar mass of NaOH was solve in section A to be 40 g/mol.

## How many moles are in 11.5 g of NaOH?

The molar mass of Na is equal to 23g/mol. The formula to find out the number of moles is given by . Therefore the number of moles in 11.5g of sodium or Na is equal to which gives us **0.5**.

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

How many moles are in 40 grams of NaOH? Now take 120 grams NaOh and multiply this by 1 mol NaOH/ 40 grams NaOH. You can cancel out the grams and you have moles left. Now you do 120 x 1 / 40 and you get **3 moles** of NaOH!

## How many moles of NaOH are present in 27 ml of 0.015 M NaOH?

=**0.045** (ans).
