Answer

Explanation:

Step1: Calculate molar - mass of (CH_2O_2)

The molar - mass of (C = 12.01\ g/mol), (H=1.01\ g/mol), (O = 16.00\ g/mol). For (CH_2O_2), (M=(1\times12.01)+(2\times1.01)+(2\times16.00)=12.01 + 2.02+32.00 = 46.03\ g/mol). To convert moles to mass, we use the conversion factor (\frac{46.03\ g\ CH_2O_2}{1\ mol\ CH_2O_2}). We want to cancel out the mole unit in (10.0\ mol\ CH_2O_2).

Step2: Determine the correct factor

We multiply (10.0\ mol\ CH_2O_2) by (\frac{46.03\ g\ CH_2O_2}{1\ mol\ CH_2O_2}). So the number that goes in the green box to cancel out the mole unit is (46.03\ g\ CH_2O_2).

Answer:

A. (46.03\ g\ CH_2O_2)
