What is the maximum mass of glucose (C6H12O6) that can be burned in 10 g of oxygen?

Dahasolnce [82]

$C_6H_{12}O_6 + 6 \ O_2 \to 6 \ CO_2 + 6 \ H_2O$
1 mole of glucose : 6 moles of oxygen

First calculate the number of moles of oxygen in 10 g:
$M=32 \ \frac{g}{mol} \\
m=10 \ g \\
n=\frac{10 \ g}{32 \ \frac{g}{mol}}=0.3125 \ mol$

1 mole of glucose reacts with 6 moles of oxygen
x moles of glucose reacts with 0.3125 moles of oxygen
$x=\frac{1 \ mol \cdot 0.3125 \ mol}{6 \ mol} = \frac{3125}{60000} \ mol= \frac{5}{96} \ mol$

Now calculate the mass of 5/96 moles of glucose.
$M=180 \ \frac{g}{mol} \\
n=\frac{5}{96} \ mol \\
m=180 \ \frac{g}{mol} \cdot \frac{5}{96} \ mol=\frac{900}{96} \ g=9.375 \ g$

The maximum mass of glucose that can be burned in 10 g of oxygen is 9.375 g.

SOLVE Use the density formula to solve the following problems. A sample of a substance has a volume of 60.5 mL and a density of

Likurg_2 [28]

Density = Mass/Volume
Therefore, Mass = Density x Volume

So the mass of the sample is 1.20 g/mL x 60.5 mL = 72.6 g
