How many moles of CO2 are in 58.5 g of carbon dioxide? 4 points
2.72 mol CO2
1.07 mol CO2
3.42 mol CO2
1.83 mol CO2

Just divide 58.5 grams by the molar mass of CO2. Use the periodic table to find the masses of C and O

Molar mass of CO2 = 12.01(1) + 16(2) = 12.01+32 = 44.01 g/mol

mol of CO2 = 58.5g/44.01 g/mol = 1.329 mol = 1.33 mol with correct sig figs

Alpha particles have positive charge, beta particles have negative charge, and answer 4 just doesn’t make sense. thus, you are left with only one possible answer.
