Show the calculation of the molecular weight for the following
compounds, reporting your answer to 2 places after the decimal.



1. Al2(SO4)3



2. C7H5NOBr


Your Answer:

1. Al2(SO4)3

Al = 2 x 26.98 = 53.96

S = 3 x 32.07 = 96.21

O = 12 x 16.00 = 192
1/18

,Total Molecular Weight for Al2(SO4)3 = 342.17



2. C7H5NOBr

C = 7 x 12.01 = 84.07

H = 5 x 1.008 = 5.04

N = 1 x 14.01 = 14.01

O = 1 x 16.00 = 16.00

Br = 1 x 79.90 = 79.90

Total Molecule Weight for C7H5NOBr= 199.02




1. 2Al + 3S + 12O = 342.17



2. 7C + 5H + N + O + Br = 199.02

Show the calculation of the number of moles in the given amount of the
2/18

, following substances. Report your answerto 3 significant figures.



1. 13.0 grams of (NH4)2CO3


2. 16.0 grams of C8H6NO4Br


Your Answer:

Moles = grams / Molecular Weight

1. 13.0 grams of (NH4)2CO3

Moles = 13.0 g / 96.094 = .135 moles of (NH4)2CO3

N = 2 x 14.01 = 28.02

H = 8 x 1.008 = 8.064

C = 1 x 12.01 = 12.01

O = 3 x 16 = 48

Molecular weight is 96.094



2. 16.0 grams of C8H6NO4Br

Moles = 16.0 g / 260.038 = .0615 moles of C8H6NO4Br

C = 8 x 12.01 = 96.08

H = 6 x 1.008 = 6.048

N = 1 x 14.01 = 14.01

O = 4 x 16.00 = 64

Br = 1 x 79.90 = 79.90

Molecular weight of C8H6NO4Br = 260.038
