The mass of carbon dioxide that would be needed to weigh is 462 grams.
Given:
10.5 moles of carbon dioxide.
The periodic table
To find:
The mass of carbon dioxide would be needed to weigh out to make 10.5 moles of carbon dioxide.
Solution:
Mass of carbon dioxide needed = m
Moles of carbon dioxide needed = 10.5 mol
The molar mass of carbon dioxide = M
The atomic mass of carbon atom = 12.011 g/mol
The atomic mass of oxygen atom = 15.999 g/mol
[tex]M = 1\times 12.011 g/mol+2\times 15.999 g/mol\\\\=44.009 g/mol[/tex]
The moles of carbon dioxide will be given as:
[tex]10.5 mol=\frac{m}{44.009 g/mol}\\\\m=10.5 mol\times 44.009 g/mol=462.0945 g\approx 462 g[/tex]
The mass of carbon dioxide that would be needed to weigh is 462 grams.
