Chapter 3: Q3.26P (page 132)

Propane is widely used in liquid from as a fuel for barbecue grills and camp stoves. For 85.5g of propane, calculate
The moles of the compound;
The grams of carbon.

Short Answer

Expert verified

The Moles of Propane is $1.94 mol C_{3} H_{8}$ .
The Mass of C is $69 .90 g C$ .

Step by step solution

To Calculate the moles of propane.

The Mass of propane=85.5g

The molar mass of propane, $C_{3} H_{8}$ , is calculated below.

$\begin{matrix} M_{ω} of C_{3} H_{8} = 3 \times (M_{ω} of C) + 8 \times (M_{ω} of H) \\ = 3 \times (12 .01 \frac{g}{mol}) + 8 \times (1 .01 \frac{g}{mol}) \\ = 44 .11 \frac{g}{mol} \end{matrix}$

Multiply the given mass of propane by the reciprocal of its molar mass to get the number of moles.

Moles of propane $= 85 .5 g C_{3} H_{8} (\frac{mol C_{3} H_{8}}{44 .11 g C_{3} H_{8}})$

Therefore, The Moles of propane is $1 .94 mol C_{3} H_{8}$ .

To Calculate the mass of C

There are 3 moles of C atoms in 1 moles of $C_{3} H_{8}$ . The number of moles of C atoms in 85.5 g propane is

Moles of C $= 5 .82 mol C (\frac{3 mol C}{1 mol C_{3} H_{8}})$

Moles of C $= 5 .82 mol C$

Therefore, Multiply the calculated number of moles of carbon, C, by its molar mass which is $12 .01 \frac{g}{mol}$ .

Mass of C $= 5 .82 mol C (12 .01 \frac{g}{mol})$

Mass of C $= 69 .90 g C .$

Therefore, The Mass of C is $69 .90 g C .$
