What is the percent by mass of water in the hydrate? %
dusya [7]

Sorry I can't tell you the answer but, I can tell you something...

Dividing the mass of the water lost by the mass of hydrate used is equal to the fraction of water in the compound. Multiplying this fraction by 100 gives the percent water in the hydrate.

How to find it?

Divide the mass of the water lost by the mass of hydrate and multiply by 100. The theoretical actual percent hydration percent water can be calculated from the formula of the hydrate by dividing the mass of water in one mole of the hydrate by the molar mass of the hydrate and multiplying by 100.

What solid can be formed from a net diagram that has 2 congruent circles and 1 rectangle?
Serggg [28]

Answer: Option (B) is the correct answer.

Explanation:

When two circles are of same same then they are known as congruent circles.

Whereas a rectangle is a kind of parallelogram with all sides equal to 90^{o}.

Therefore, when 2 congruent circles and 1 rectangle combines then it results in the formation of a cylinder.

Thus, we can conclude that solid formed when 2 congruent circles and 1 rectangle combines will be a circle.
