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
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
