Do this i am in need

Answer 1

Percentage of calcium in calcium oxide us near about 54.1 to 54.3

Answer 2

Hi,

Prasika

How are you?

Here is your answer

Molar mass of Calcium is 40.078

Molar mass of Oxygen is 15.9994

Molecular Weight Calculation:

Molar mass of Calcium Oxide is 40.078 + 15.9994 = 56.0774 g / mole

Percentage by Weight: Mass of the element : 1 mole
-----------------------------------------------------------------------------*100
Total Molecular weight of the Compound (1 mole )


Percentage of Calcium in Calcium Oxide :-) 40.078
----------------------------- * 100
40.078 + 15.9994

Percentage of Calcium in Calcium Oxide :-) 40.078
----------------------------- * 100
56.0774

Percentage of Calcium in Calcium Oxide = 0.714691 * 100 (simplify 40.078
( ------------------
( 56.0774

By Multiplying, we get that :)

Percentage of Calcium in Calcium Oxide is 71.469077 %

Hoping it helps you

:D
