How many moles are in 80g 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 in 40g sodium hydroxide 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 much sodium can be obtain from 80g of NaOH?

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 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 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 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 there in 60g of NaOH?

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

How many grams is 4.00 moles 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.

How many particles are in 7.5 moles?

Explanation: And Avogadro’s number , 6.022×1023⋅mol−1 specifies a molar quantity…… And so 7.5⋅mol×6.022×1023⋅mol−1≅4.5×1024 sulfur atoms .
