Question

Calculate the mass of N in 200g Mass of KNO3

Answer 1

${\huge {\mathfrak {Answer :-}}}$

Molecular mass of KNO3

= 39 + 14 + 3 * 16

= 39 + 14 + 48

= 101.

Now, we have,

14 g N in 101 g of KNO3

1 g of KNO3 = 14/101 g of N

➡️ 200 g of KNO3 = 14/101 * 200 g N

= 2800/101 g of N.

$<b>200 g of KNO3 contains 2800/101 g of N. </b>$

$<i>$ That's it..
