Calculate the molecular weight of the following H2O2, HNO3​

Answer»

ong>Answer:

CALCULATE molar mass of h2o2 and HNO3

Molar mass of hydrogen peroxide (H2O2) = 2(mass of hydrogen) + 2(mass of oxygen) = 2 x 1 + 2 x 16.

= 34g.

Molar mass of Nitric Acid (HNO3) = mass of hydrogen + mass of nitrogen + 3(mass of oxygen)

= 1 + 14 + 3 x 16 = 63g.

Hope it's HELPFUL for you
