Question

How many moles are in 36.0g of H20

Answer 1

Answer:

The answer to your question is 2 moles

Explanation:

Data

mass of H₂O = 36 g

moles of H₂O = ?

Process

1.- Calculate the molar mass of water (H₂O)

H₂O = (1 x 2) + (16 x 1) = 2 + 16 = 18 g

2.- Use proportions and cross multiplication to find the answer.

               18 g of H₂O ---------------- 1 mol

               36 g of H₂O --------------- x

                     x = (36 x 1) / 18

                     x = 36/18

                     x = 2 moles

Answer 2

For every 18.015 g of water you have 1 mole of water, do the math 36 g • 1 mol h20/ 18.015 g = 2.0 moles
