Question

no. of electrons in 32g so2​

Answer 1

Answer:

Divide the given mass by the molecular weight of SO2 to get number of moles (n), then multiply moles by Avogadro's number to get number of molecules (N).

Atomic weights:

S = 32.07 g/mole

O = 16.00 g/mole

Molecular weight:

SO2 = 32.07 + 2(16.00) = 64.07 g/mole

n = (32 g) / (64.07 g/mole) = 0.49945 moles

N = nA = (0.49945 moles) (6.02 x 1023 molecules/mole) = 3.007 x 1023 molecules

There are about 3.007 x 1023 molecules of SO2 in 32 g of SO2 and there are 9228.483 atoms....
