A 118.63 g sample of SrCl2·6H2O was heated and 34.81 grams of water were recovered from the sample. What percent of the original H2O remains in the sample following this heating?

Question

anonymous · Answer

Find % of water by mass for the sample
Find % of water in your sample after boiling
Subtract to find the answer (remains)

anonymous · Answer

so i first do 34.81 x 1mol H2O/ mw H2O x 100

anonymous · Answer

nvm thats for after.

anonymous · Answer

i dont know how to set a problem to find the 1st part..

anonymous · Answer

You take the mass of the water in the original formula divided by the total molecular mass
So mass of (6 H2O)/(Sr Cl2 6 H2O)
