Answer
a. 46.0 g
b. 112 g
c. 14.8 g
d. 112 g
Work Step by Step
- Calculate or find the molar mass for the compound:
a. ( 22.99 $\times$ 1 )= 22.99 g/mol
b. ( 40.08 $\times$ 1 )= 40.08 g/mol
c. ( 118.7 $\times$ 1 )= 118.7 g/mol
d. ( 63.55 $\times$ 1 )= 63.55 g/mol
- Using the molar mass as a conversion factor, find the mass in g:
a. $$ 2.00 \space mole \times \frac{ 22.99 \space g}{1 \space mole} = 46.0 \space g$$
b. $$ 2.80 \space mole \times \frac{ 40.08 \space g}{1 \space mole} = 112 \space g$$
c. $$ 0.125 \space mole \times \frac{ 118.7 \space g}{1 \space mole} = 14.8 \space g$$
d. $$ 1.76 \space mole \times \frac{ 63.55 \space g}{1 \space mole} = 112 \space g$$
