Question

calculatethe percentage compostion of calcium nitrate [ Ca = 40 ,N =14 , O = 16​

Answer 1

Answer:

hope it helps

Explanation:

please mark me as brainlist

Answer 2

total mass = 40 + 40 + 14 + 3 × 16 = 142 u

Ca = 80/142×100 = 56 %

N = 14/142×100 = 10 %

O = 48/142×100 = 34%

I've done it according to given formula for ur practise

Ca(NO³)

Now, using this u can solve self, Calcium Nitrate = Ca(NO³)²

this will improve your practising numericals
