1. Find the molar mass (MM) of the substances.
MM FeSO4 = 151.91g
+MM 7H2O = 126.11g
MM FeSO4 x 7H2O = 278.02g
2. Find the percent water of hydrate.
Divide the mass of water by the mass of the hydrate; multiply result by 100%.
126.11g
278.02g x 100%
Percent water of FeSO4 * 7H2O is 45.36%.
Finding Molar Mass
# atoms Element A x Atomic Mass Element A = Mass A
# atoms Element B x atomic mass Element B = Mass B
... etc.
Add up all the mass values for the substance and you have the molar mass of the substance.

How would you find the percent of 17g sucrose in 188g of water?
To find the percent of 17g sucrose in 188g of water, first calculate the total mass: 17g (sucrose) + 188g (water) = 205g. Then, divide the mass of sucrose (17g) by the total mass (205g), and multiply by 100 to convert to a percentage. The percent of 17g sucrose in 188g of water would be roughly 8.29%.
What is the concentration in mm percent of a solution prepared from 50.0g Na-Cl and 150.0g of water?
To find the concentration in mass percent, first calculate the total mass of the solution (50.0g NaCl + 150.0g water = 200.0g total). Then, divide the mass of NaCl by the total mass of the solution and multiply by 100 to get the concentration in mass percent: (50.0g NaCl / 200.0g total) * 100 = 25.0% NaCl.
The molarity of a 5 percent solution of NH3 in water?

Calculate The percent Water In CoC2H3O22 x 4H2O?
To calculate the percent water in Co(C2H3O2)2 x 4H2O, first find the molar mass of Co(C2H3O2)2 x 4H2O: 58.93 (Co) + 2*(12.01 (C) + 1.01 (H) + 16.00 (O)) + 4*(18.02 (H2O)). The molar mass is 237.02 g/mol. Next, calculate the molar mass due to water: 4*(18.02) = 72.08 g/mol. The percent water is calculated by (molar mass of water in formula / molar mass of compound) x 100: (72.08 / 237.02) x 100 = 30.42%.
How do you calculate the percent water in a hydrate?
To calculate the percent water in a hydrate, you first determine the mass of water in the hydrate by subtracting the mass of the anhydrous compound from the mass of the hydrate. Then, divide the mass of water by the total mass of the hydrate and multiply by 100 to get the percentage.
