Answer 1

Answer:

pls mark me as the brainliest

Explanation:

a) 1 mole = molecular mass = 6.022 x 10^23

Gram molecular mass of SO2 = (32x1) + (2x16) = 64 g

64 g of SO2 have molecules = 6.022 x 10^23 molecules

44 g of SO2 have molecules = 6.022 x 10^ 23/64 x 44 = 3.76 x 10^23 molecules

b) we know that 1 mole of oxygen contains 6.022 x 10^23 oxygen atoms.

Hence, 1 atom of oxygen molecules weighs = 3.76 x 10^-23
