Question

How many carbon atoms are there in 52.06 g of carbon dioxide?

Answer 1

The molar mass of carbon dioxide is about \[44\text{g/mol}\]because\[CO_{2}=1\text{mol}C*12\text{g/mol}+\text{2mol}O_{2}*16\text{g/mol}\]find the number of moles of carbon dioxide and multiply that by Avogadro's number \[\#\text{molecules}={52.06\over 44}*6.02*10^{23}=7.123*10^{23}\]
