APFIVE Calculating Mass from Moles
A chemist analyzes a compound and determines its molecular formula is C₂H₆O. If the average mass of one molecule of this compound is 46.07 amu, which calculation would correctly determine the mass of 2.50 moles of this compound?
A
2.50 mol × (46.07×6.022×10^23) g = 6.94×10^25 g
B
2.50 mol × (46.07/6.022×10^23) g = 1.91×10^-22 g
C
2.50 mol ÷ 46.07 g/mol = 0.0543 g
D
2.50 mol × 46.07 g/mol = 115.18 g
