How would I find the percent of water lost in alum after it has dried for a week?
Wet Alum = 13.44g
Dry Alum = 11.28g
I believe you would subtract the dry weight of the alum from the wet alum weight, then divide that answer by the original weight of wet alum:
13.44g(wet) - 11.28g (dry) = 2.16g of water that was lost.
2.16g H20/ 13.44g wet alum =0.1607 X 100 = 16.07% H20 lost
Hope this helps :)
To find the percent of water lost in alum, you need to calculate the difference in weight between wet alum and dry alum and then express it as a percentage of the initial weight of wet alum.
Step 1: Calculate the weight of water lost
Water lost = Weight of wet alum - Weight of dry alum
Water lost = 13.44g - 11.28g
Water lost = 2.16g
Step 2: Calculate the percentage of water lost
Percentage of water lost = (Water lost / Weight of wet alum) x 100
Percentage of water lost = (2.16g / 13.44g) x 100
Percentage of water lost = 16.07%
Therefore, the percent of water lost in the alum after it has dried for a week is approximately 16.07%.
