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: Thus X is Plutonium
Explanation:
Alpha Decay: In this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. The mass number is reduced by 4 units and atomic number is reduced by 2 units.
General representation of alpha decay :
where Z = atomic number
A= mass number
X and Y = atomic symbol of elements
Thus
Thus X is Plutonium with atomic number 94 and mass number 239
