Answer:
20 g of CO₂ have 5.47x10²³ oxygen atoms
Explanation:
1 mol of CO₂ has 1 mol of C and 2 moles of O.
Mass / Molar mass = Moles
20 g / 44 g/m = 0.454 moles
In 1 mol we find 2 moles of O
In 0.454 moles of CO₂, we will find ( 0.454 .2) = 0.909 moles
1 mol has _____ 6.02x10²³ atoms
0.909 moles have (0.909 . 6.02x10²³) = 5.47x10²³ atoms
