Question

determine the number of molecules of SO2 Containing 16g of oxygen​

Answer 1

Answer:

the answer is 3.011×10²³

mass of SO2 = MASS OF SULPHUR ATOMS+ MASS OF O2 ATOMS

=32+16×2=64

NUMBER OF O ATOMS IN SO2 = GIVEN MASS OF OXYGEN/ MOLAR MASS OF SO2 × AVAGADRO NUMBER

=16/64× 6.022×10²³=1.5055×10²³

THERE ARE 2 ATOMS OF O IN SO2

=2×1.5055×10²³=3.011×10²³
