Question: How many moles are there in 80 grams of NaOH?

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 moles are there in 60 grams of NaOH?

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

How many moles are in 20 grams of NaOH?

Answer: Number of moles which make up 20 grams of NaOH = (20 grams × 1 Mole)/(40 grams) = 0.5 moles.

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 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 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.
