Answer:

A. 1.377 g

B. 16.5%

Explanation:

To find the water loss, subtract the salt and crucible mass from the hydrate and crucible mass

21.018 - 19.641 = 1.377

To find the water mass percentage, divide the empty crucible mass by the mass of the hydrate and crucible. Then, subtract that number from 1.

17.556 ÷ 21.018 = 0.835284

1 - 0.835284 = 0.164716

If you want to add an extra step, multiply this number by 100 to get the percentage.

0.164716 x 100 = 16.4716
