Answer #1

A)

Molar mass of C20H21FN2O,

MM = 20*MM(C) + 21*MM(H) + 1*MM(F) + 2*MM(N) + 1*MM(O)

= 20*12.01 + 21*1.008 + 1*19.0 + 2*14.01 + 1*16.0

= 324.4 g/mol

Answer: 324.4 g/mol

B)

Molar mass of CaC12H22O14,

MM = 1*MM(Ca) + 12*MM(C) + 22*MM(H) + 14*MM(O)

= 1*40.08 + 12*12.01 + 22*1.008 + 14*16.0

= 430.4 g/mol

Answer: 430.4 g/mol

C)

Molar mass of C3H8O,

MM = 3*MM(C) + 8*MM(H) + 1*MM(O)

= 3*12.01 + 8*1.008 + 1*16.0

= 60.09 g/mol

Answer: 60.09 g/mol

D)

Molar mass of C18H20FN3O4,

MM = 18*MM(C) + 20*MM(H) + 1*MM(F) + 3*MM(N) + 4*MM(O)

= 18*12.01 + 20*1.008 + 1*19.0 + 3*14.01 + 4*16.0

= 361.4 g/mol

Answer: 361.4 g/mol
