Question

Solve the following conversion problems. Look out for “How many…” Remember: If the answer is in grams, multiply. If it’s in moles, divide.

Answer 1

9.
`14.01 \, \text{g}`

10.
`624.69 \, \text{g}`

11.
`\approx 74.10 \, \text{g/mol}`

`111.15 \, \text{g}`

12.
`174.12 \, \text{g/mol}`

`348.24 \, \text{g}`

13.
`\approx 1.996 \, \text{mol}`

14.
`\approx 3.12 \, \text{mol}`

15.
`\approx 0.5 \, \text{mol}`

16.
`\approx 2 \, \text{mol}`

How did we get these values?

Let's go through the calculations:

9.
`\[ 28.02 \, \text{g/mol} * 0.5 \, \text{mol} = 14.01 \, \text{g} \]`

10.
`\[ 137.33 \, \text{g/mol} + 2 * 35.45 \, \text{g/mol} = 208.23 \, \text{g/mol} \]`

`\[ 3 \, \text{mol} * 208.23 \, \text{g/mol} = 624.69 \, \text{g} \]`

11.
`\[ 40.08 \, \text{g/mol} + 2 * (1.01 \, \text{g/mol} + 15.999 \, \text{g/mol}) \approx 74.10 \, \text{g/mol} \]`

`\[ 1.5 \, \text{mol} * 74.10 \, \text{g/mol} = 111.15 \, \text{g} \]`

12.
`\[ 2 * (22.99 \, \text{g/mol} + 2 * 15.999 \, \text{g/mol} + 32.07 \, \text{g/mol}) = 174.12 \, \text{g/mol} \]`

`\[ 2 \, \text{mol} * 174.12 \, \text{g/mol} = 348.24 \, \text{g} \]`

13.
`\[ \frac{34 \, \text{g}}{17.03 \, \text{g/mol}} \approx 1.996 \, \text{mol} \]`

14.
`\[ \frac{183 \, \text{g}}{58.69 \, \text{g/mol}} \approx 3.12 \, \text{mol} \]`

15.
`\[ \frac{171 \, \text{g}}{342.3 \, \text{g/mol}} \approx 0.5 \, \text{mol} \]`

16.
`\[ \frac{454 \, \text{g}}{227.1 \, \text{g/mol}} \approx 2 \, \text{mol} \]`
