8. What is the molar mass of carbon dioxide, Co2(g)? How many grams of carbon
1 answer:
Answer:
CO2 molar mass=44.01g
3 moles CO2 = 132.03g
Explanation:
CO2 molar mass = 12.01+2(16.00)=44.01g
3 moles CO2 * (44.01 g CO2)/(1 mol CO2)=132.03g
(Answer would be different depending on the number of decimals)

Explanation:</h3>
- The nuclear equation shows the decay of Radon-222 by emitting an alpha particle to form polonium-218.
- When a radioactive isotope undergoes alpha-decay, the mass number is decreased by 4 while the atomic number decreases by 2.
- Therefore, the complete nuclear equation is;
²²²₈₆Rn → ²¹⁸₈₄Po + ⁴₂He
- The atomic number of Radon-222 decreases from 86 to 84 while the mass number decreases from 222 to 218, forming polonium-218.

Answer:
264 g/mol
Explanation:
#electrons equal #protons = 106
Plus 1 charge => m protons = 106 + 1 = 107
Mass number: 107 + 157 = 264 g/mol
