How many molecules of carbon dioxide are in 243.6 g of carbon dioxide

Chemistry
1 answer:
rewona [7]3 years ago
4 0

Answer:

Explanation:

First, lets find the molar mass of CO². This is approximately 12 + 2(16) = 44 g/mol. Now, let's set up the conversions.

                                                         This is Avogadro's number

                                                                        ↓

243.6g CO² * (1 mol CO² /44g CO²) * (6.023 * 10^23 molecules/ 1 mol)

When we cancel out the units, we are left with 3.33 * 10^23 molecules of carbon dioxide. I hope this makes sense!
