How many molecules of CO₂ are present in 33.6 g of CO₂?

Question

Quizplus · Accepted Answer

To find the number of molecules in 33.6 g of COS, we first need to calculate the molar mass of COS. The molar mass of carbon (C) is approximately 12 g/mol, oxygen (O) is 16 g/mol, and sulfur (S) is 32 g/mol. Adding these together, the molar mass of COS is 60 g/mol. Using Avogadro's number (6.022 x 10^23 molecules/mol), the number of molecules in 33.6 g of COS can be calculated as follows: (33.6 g / 60 g/mol) * (6.022 x 10^23 molecules/mol) = 3.36 * 6.022 x 10^23 = 2.023 x 10^24 molecules. The choice that most closely matches this calculation is B, which suggests a value in the same order of magnitude, considering the format of the options provided.
