Determine the mass in units of grams [g] of 0.49 moles [mol] of a new fictitious compound you have developed in the lab. The formula is A2B4C8D5 The components are A amu=3;B,amu=26;C,amu=36;and D,amu=52.
Homework Answers
Molar mass of A2B4C8D5 = 2*MM(A) + 4*MM(B) + 8*MM(C) + 5*MM(D)
= 2*3 + 4*26 + 8*36 + 5*52
= 658 g/mol
now use:
mass = number of mol * molar mass
= 0.49 mol * 658 g/mol
= 322 g
Answer: 322 g
