How many mols in 22.45g of water?

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

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

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
