Answer
a. 29.2 g
b. 108 g
c. 4.05 g
d. 195 g
Work Step by Step
- Calculate or find the molar mass for the compound:
a. ( 22.99 $\times$ 1 )+ ( 35.45 $\times$ 1 )= 58.44 g/mol
b. ( 22.99 $\times$ 2 )+ ( 16.00 $\times$ 1 )= 61.98 g/mol
c. ( 1.008 $\times$ 2 )+ ( 16.00 $\times$ 1 )= 18.02 g/mol
d. ( 12.01 $\times$ 1 )+ ( 16.00 $\times$ 2 )= 44.01 g/mol
- Using the molar mass as a conversion factor, find the mass in g:
a. $$ 0.500 \space mole \times \frac{ 58.44 \space g}{1 \space mole} = 29.2 \space g$$
b. $$ 1.75 \space mole \times \frac{ 61.98 \space g}{1 \space mole} = 108 \space g$$
c. $$ 0.225 \space mole \times \frac{ 18.02 \space g}{1 \space mole} = 4.05 \space g$$
d. $$ 4.42 \space mole \times \frac{ 44.01 \space g}{1 \space mole} = 195 \space g$$
