Question

Calculate the mass of 18.069 x 10^23 molecules of so2

Answer 1

Hi there,

■ Given:

☆ Number of SO2 molecules = 18.069×10^23

☆ Molar mass of SO2 = 64 g/mol

☆ Avogadro's number = 6.02×10^23

● The mass of SO2 =

number of molecules × Mwt ÷ avogadro's number

● 18.069×10^23 × 64 ÷ (6.02×10^23)= 192.09 gm
