Question

How many mols in 22.45g of water?

Answer 1

Answer:

Explanation:

Explanation

Periodic tables vary in how many places of sig digits they show. I always use approximate values which means that you will have to redo the question using your values

Water (1 mole)

2 * H =  1.01 * 2 = 2.02

1 * O = 16 * 1 =   16.00

Mass 1 mole =   18.02

Moles water

given mass = 22.45

molar mass = 18.02

moles = given mass/ molar mass

moles = 22.45 / 18.02

moles = 1.246 moles

Answer 2

Answer:

1.247mol

Explanation:

moles=mass/molar mass

molar mass of water = 1+1+16=18

mass = 22.45

22.45÷18

= 1.247 moles of water
