Took a crucible, weighed it (53.200 g). Then added 5 g of an unknown hydrate compound and weighed that (58.075 g). Then took the Bunsen burner put it on low flame and heated it for 30 seconds and then weighed that (56.316 g)
Calculate the following and show calculations :
(a) mass of hydrated compound before heating (g)
(b) mass of dry salt after heating (g)
(c) mass of water in the hydrate sample (g):
(d) percent by mass of water in the sample:
Then in the second part i did the exact thing but adding 10 g into the crucible which came to (62.950 g) and after heating it for 30 sec the mass was (59.433 g)
Calculate the following and show calculations :
(a) mass of hydrated compound before heating (g)
(b) mass of dry salt after heating (g)
(c) mass of water in the hydrate sample (g):
(d) percent by mass of water in the sample: |
