Question

(b) Calculate the relative molecular mass of the following: (a) CHCl3​

Answer 1

Answer:

Atomic mass of C = 12 u

Atomic mass of H = 1 u

Atomic mass of Cl = 35.5 u

Therefore, molecular mass of CHCl3 can be calculated as follows:

(1 × 12) + (1 × 1) + (3 ×35.5) = 119.5

hope it helps.☺

plz let me know if its wrong

Answer 2

Answer:

118 u

Explanation:

molecular mass of C= 12

molecular mass of H = 1

molecular mass of Cl = 35

therefore, molecular mass of CHCl3 =

12+ 1+(3×35)

= 12+1+105

=118
