What is the number of moles in 5.67g of potassium hydroxide?

Answer 1

atoms are in 5.00x10^-2 moles of krypton is 1013.9558

Answer 2

To find the number of moles in 5.67g of potassium hydroxide, divide the mass by the molar mass of KOH. The molar mass of KOH is approximately 56.11 g/mol. Therefore, 5.67g / 56.11 g/mol = 0.101 moles of potassium hydroxide.

Answer 3

If the mole size or formula weight is a single atom, (5.75 X 10)/(6.002 X 1023) or 9.55 X 10-23 moles, to the justified number of significant digits.

Answer 4

The formula mass of potassium hydroxide, KOH is 39.1+16.0+1.0=56.1

Amount of KOH = 5.67/56.1 = 1.01mol

There are 1.01 moles of KOH in a 5.67 gram sample.

Answer 5

I mole of any substance contains 6.023 X 1023 particles. Thus 5.7 X 1023 is 5.7/6.023 = 0.946 of a mole.
