Question

what mass of C0² will contain some number of atoms as are contained in 20 gram of oxygen molecule?​

Answer 1

Answer:

Molecular mass of CO2 = 1(12) +2(16)

=12 + 32

=44 g

16 g of oxygen =6.022×10²³atoms

1 g of oxygen = [6.022×10²³/16] atoms

20 g of oxygen =[(6.022×10²³/16)×20] atoms

= 7.5275 × 10²³ atoms
