What mass of CO2 would be needed to weigh out to make 10.5 moles of carbon dioxide? (round answer to nearest tenth)
melamori03 [73]

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

M = 1\times 12.011 g/mol+2\times 15.999 g/mol\\\\=44.009 g/mol

The moles of carbon dioxide will be given as:

10.5 mol=\frac{m}{44.009 g/mol}\\\\m=10.5 mol\times 44.009 g/mol=462.0945 g\approx 462 g

The mass of carbon dioxide that would be needed to weigh is 462 grams.
