Answer 1

Ans: Formula unit mass of NaHCO3 =
=(Number Sodium atoms * atomic mass of sodium) + (Number Hydrogen atoms * atomic mass of Hydrogens) (Number Carbon atoms * atomic mass of Carbon) + (Number Oxygen atoms * atomic mass of Oxygen)
= (1*23) + (1*1)+(1*12) + (3*16)
= 23+1+12+48
=84
Formula unit mass of baking soda = 84
