Question

calculate the relative molecular mass of potassium nitrate [AT wt :potassium = 39 , nitrogen = 14 , oxygen = 16

Answer 1

Atomic Weight,

Potassium (K) : 39 g

Nitrogen (N) = 14 g

Oxygen (O) = 16 g

Molar Mass of Potassium Nitrate = KNO₃

= 39+14+48 g

= 101 g (Answer)

I hope this helps.
