Question

calculate molar masses of compounds give below 1) Na oH 2) HCI (Na-23, H-1 , O-16, CI-35​

Answer 1

Explanation:

atomic mass of Na-23u

". ". ". O-16u

". ". ". H-1u

". ". ". Cl-35u

1)molar mass of NaOH-(23×1)+(16×1)+(1×1)

=23+16+1

=40u

2)molar mass of HCl-(1×1)+(35×1)

=1+35

=36u

Answer 2

1) NaOH

Sodium hydroxide is NaOH .

Thus, its molar mass involves:

M Na = 22.989 g/mol

M O = 15.999 g/mol

M H = 1.0079 g/mol
