a. Cyclopropane, C3H6, is an anesthetic given by

Solution 38QPStep 1 of 2:a. Here, we are asked to calculate the mass (in grams) in 0.25 mole of cyclopropane (C3H6). Given:Number of moles of C3H6 = 0.25 molesMass of C3H6 =Molar mass of C3H6 = 42.08 g/molSo, 1 mole of C3H6 = 42.08 gSo, the mole-mass factor will be: and We know the formula to calculate the number of moles:Number of moles = This can be rewritten as:mass of the compound = number of moles molar mass of the compound = 0.25 moles of C3H6 = 10.52 g 11 gramsHence, the mass of C3H6 in 0.25 moles of C3H6 is 11 grams.________________
