To determine which sample has the greatest mass, we calculate the mass of each sample using the formula: mass = moles × molar mass. The molar mass of each substance is as follows: camphor (C10H16O) ≈ 152 g/mol, ammonia (NH3) ≈ 17 g/mol, krypton (Kr) ≈ 83.8 g/mol, iodine vapor (I2) ≈ 254 g/mol, and formaldehyde (CH2O) ≈ 30 g/mol. Calculating the mass for each: A) 0.37 mol × 152 g/mol = 56.24 g, B) 4.2 mol × 17 g/mol = 71.4 g, C) 9.3 mol × 83.8 g/mol = 779.34 g, D) 4.0 mol × 254 g/mol = 1016 g, E) 1.6 mol × 30 g/mol = 48 g. Therefore, 4.0 mol of iodine vapor has the greatest mass.
