Question

calculate the molecular mass by Na2CO3(at mass =Na=23 c=12 O=16)

Answer 1

Molecular Mass of Na2CO3 :-

23×2+12+16×3

46+12+48

106 atomic unit (atm.)

is the answer

Answer 2

Answer:

106. The atomic mass numbers of the different chemicals are provided in the question, i.e., Sodium-23, Carbon-12 and Oxygen-16.

Hence, for determining the molecular mass of this compound, we have to multiply the atomic mass numbers with the number of molecules that are present in it.

Hence, the molecular mass of the compound is (23X2)+(12X1)+(16X3) which is equal to 106.
