please review and show the calculations. also i need the average percent of water (8).Thank youuu
Homework Answers
Hi,
Hope you are doing well.
CALCULATIONS:
3. Mass of unknown hydrate sample (#2-#1)=79.28 g-78.22 g=1.06 g
4. Mass of unknown anhydrate sample and beaker (after heating) =79.36 g
5. Mass of anhydrous sample (#4-#1)=79.36 g-78.22 g=1.14 g
6. Mass of water lost from sample (#3-#5) =1.06 g-1.14 g=0.08g
7. Average mass of water lost from sample= (0.08 g+0.72 g)/2=0.4 g
8. Average percent of water in the sample=
