Question

Calculate the mass of 3 g molecules of HNO3​

Answer 1

Hey mate here's your answer

molar mass of HNO3 = 1 + 14 + 48 = 63 g or more precisely it is 63.0128 grams

3 moles = 3 x 63 g = 189 grams. That would be the mass.

Answer 2

Answer:

3.1 *10power -24

Explanation

formula mass of hno3= 63g

hence 63g = avogrado no molecules

weight of 1 molecule= 63/avogrado no

now using this relation we can  find weight of 3 g molecules
