TaigaTo calculate the percent by mass of each compound, you need to know their molar masses. For CuSO4•5H2O (copper(II) sulfate pentahydrate), the molar mass is 249.68 g/mol. For MgSO4•7H2O (magnesium sulfate heptahydrate), the molar mass is 246.47 g/mol. Now, divide the molar mass of each compound by the sum of the molar masses of both compounds and multiply by 100 to get the percent by mass. This will give the percentage composition of each compound within the mixture.

What is the cation of MgSO4 plus 7H2O?
The cation of MgSO4·7H2O is Mg^2+ (magnesium ion).
What is the total number of oxygen atoms in the formula mgso47 h2o?
The formula given is mgSO4 * 7H2O. This means there are 4 oxygen atoms in MgSO4 and 14 oxygen atoms in 7H2O, giving a total of 18 oxygen atoms in the entire formula.
What is the symbol for magnesium sulfate heptahydrate?
The symbol for magnesium sulfate heptahydrate is MgSO4•7H2O.
If 5.742g of hydrated magnesium sulfate is heated 2.801g of anhydrous magnesium sulfate remains Determine the formula of the hydrated form?
The formula of the hydrated form is MgSO4·7H2O. To find this, calculate the molar mass of MgSO4 (120.37 g/mol) and compare it to the molar mass of MgSO4·7H2O (246.47 g/mol). The difference in mass represents the mass of water lost upon heating, which is 126.1 g/mol (246.47 g/mol - 120.37 g/mol). Dividing the mass of water lost by the molar mass of water (18.015 g/mol) gives us the number of water molecules in the hydrated form.
What is the percent composition of magnesium sulfate in magnesium sulfate heptahydrate?
