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
The moles of carbon dioxide will be given as:
The mass of carbon dioxide that would be needed to weigh is 462 grams.

Answer: Balanced molecular equation :
Total ionic equation:
The net ionic equation:
Explanation:
Complete ionic equation : In complete ionic equation, all the substances that are strong electrolyte are present in an aqueous state as ions.
Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.
Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.
When sodium phosphate and zinc acetate then it gives zinc phosphate and sodium acetate as product.
The balanced molecular equation will be,
The total ionic equation in separated aqueous solution will be,
In this equation, and are the spectator ions.
By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.
The net ionic equation will be,
