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 80g of NaOH?
= 80 / 40= 2 mol .
How many moles are in 30g 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 of NaOH are present in 27 ml of 0.015 M NaOH?
How many moles of NaOH are contained in 30ml of its 0.15 M solution?
= 0.15 / 1000 X 27 moles. = 0.004 Moles.
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 of NaOH are present in 160g of NaOH?
Question = Calculate the moles of Sodium hydroxide contained in 160 g of it. Answer = 160 g of Sodium hydroxide. 160 g of Sodium hydroxide = 1 mol × 160 / 40 = 4 mol.
How many moles of sodium hydroxide NaOH are present in 200 g NaOH?
200 g / 40 g /mol =5 mol.
What is the number of moles in 10g of NaOH?
Answer: The answer is 39.99711.
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 .
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.
