In the previous task, you calculated the values for the hydrate mathrm(FeSO)_(4) cdot 7 mathrm(H)_(2) mathrm(O) , shown in the chart below. Using this information, answer the following questions. Type in the answers using one decimal place. M.M. mathrm(FeSO)_(4) & M.M. 7 mathrm(H)_(2) mathrm(O) & M.M. mathrm(FeSO)_(4) cdot 7 mathrm(H)_(2) mathrm(O) 151.92 mathrm(~g) / mathrm(mol) & 126.14 mathrm(~g) / mathrm(mol) & 278.06 mathrm(~g) / mathrm(mol) What is the percent by mass of water in the hydrate? square % What is the percent by mass of the anhydrous salt, mathrm(FeSO)_(4) , in the hydrate? square %

# ExplanationTo determine the percent by mass of water in the hydrate , we use the following formula: Given:- M.M. of = - M.M. of = Substituting these values into the formula: Calculating this: Next, to determine the percent by mass of the anhydrous salt in the hydrate, we use a similar formula: Given:- M.M. of = - M.M. of = Substituting these values into the formula: Calculating this: # AnswerThe percent by mass of water in the hydrate is .The percent by mass of the anhydrous salt, , in the hydrate is .
