31.54 grams − 29.52 grams = 2.02 grams {\displaystyle \ 31.54{\mbox{ grams}}-29.52{\mbox{ grams}}=2.02{\mbox{ grams}}} F ( x ) = x 2 {\displaystyle \ F(x)=x^{2}}
18 grams 1 mole = .73 grams x moles {\displaystyle \ {\frac {18{\mbox{ grams}}}{1{\mbox{ mole}}}}={\frac {.73{\mbox{ grams}}}{x{\mbox{ moles}}}}}
x = 0.041 moles {\displaystyle \ x=0.041{\mbox{ moles}}}
0.73 grams H 2 O 2.02 grams hydrate × 100 = 36 % {\displaystyle \ {\frac {0.73{\mbox{ grams }}{H_{2}}O}{2.02{\mbox{ grams hydrate}}}}\times 100=36\%}
36 − 29 29 × 100 = 24 % error {\displaystyle \ {\frac {36-29}{29}}\times 100=24\%{\mbox{ error}}}
