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 200 grams of sodium hydroxide?
200 g / 40 g /mol =5 mol.
How many moles are in 80g of NaOH?
= 80 / 40= 2 mol .
How many moles of NaOH are present in 27 ml of 0.015 M NaOH?
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 200g?
[n = 200 grams ÷ 19.0 g/mol] = 10.5 moles.
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 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.
What is the mass of 0.5 mole of sodium hydroxide?
However, in expressing the concentration as M (molarity) the volume of the solution is also taken into account. Thus, 0.5 mole of NaOH represents simply 20 g of the base while 0.5 M means 20 g of the base or NaOH dissolved per litre of the solution.
