4. A 2.000 gram sample of hydrated barium carbonate was heated to dryness and the remaining compound weighed 1.570 g. What is the mass percent of water in the hydrated sample? What is the molecular formula of the hydrated barium carbonate?

The mass percent of water in the hydrated sample is 21.5 %

Explanation:

To calculate the mass percentage of water in the hydrated sample, we use the equation:

We are given:

Mass of hydrated sample = 2.00 g

Mass of water = [2.000 - 1.570]g = 0.430 g

Putting values in above equation, we get:

Hence, the mass percent of water in the hydrated sample is 21.5 %
