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!
