Question

2. Calculate the molecular mass for the following a. Sulphuric acid b. Calcium chloride​

Answer 1

Explanation:

molecular formula of sulphuric acid is h2so4

mass of hydrogen is = 1amu

mass of sulphur is = 32 amu

mass of oxygen is = 16 amu

therefore mass of sulphuric acid = 2×1+32+4×16= 98 amu

Answer 2

Answer:

H2SO4-98u(approx)

Cacl2-110u

Explanation:

molecular mass is the sum of atomic masses of each element present in a compound

h2so4-1*2+32+16*4 h-1u s-32u o-16u

34+64=98u

cacl2-30+35.5*2

ca-40 cl-35. 5

cacl2=30+71

cacl2=110u
