calculate the percentage composition of calcium oxide (cao) given that ca=45 u 0 = 16u
Answers
Answer:
1.Ca= 80percent
2.O = 28 percent
Explanation:
percentage composition = molar mass of component /
total mass
Step 2:
answer ×. 100
total mass of CAO= 56.0774
Answer:
hey, here's your answer.
Explanation:
FORMULA:
Please refer the attached image for the formula.
You have to calculate % Composition of elements separately.
SO,
45
% of Ca = -------- ×100 [here,
61 61=45+16 (total mass]
% of Ca = 73.77
SIMILARLY,
16
% of O= ---------- ×100
61
% of O = 26.22
VERIFICATION:
Add 73.77 and 26.22
you'll get 99.99 ~ 100
you'll get 99.99 because we only took 2 decimals after dividing, if we took all of them it would be perfectly 100%.
Hope this helps you
THANKS YOU
