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

What Mass Of CO2 Would Be Needed To Weigh Out To Make 105 Moles Of Carbon Dioxide Round Answer To Nearest Tenth class=

Sagot :

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.
