Glucose, C6H12O6, is used as an energy source by the human body. The overall reaction in the body is described by the equation C

6H12O6(aq)+6O2(g)⟶6CO2(g)+6H2O(l)
Calculate the number of grams of oxygen required to convert 53.0 g of glucose to CO2 and H2O.

Answer : The mass of oxygen required are, 56.448 grams

Explanation : Given,

Mass of glucose = 53 g

Molar mass of glucose = 180.156 g/mole

Molar mass of O_2 = 32 g/mole

First we have to calculate the moles of C_6H_{12}O_6.

\text{Moles of }C_6H_{12}O_6=\frac{\text{Mass of }C_6H_{12}O_6}{\text{Molar mass of }C_6H_{12}O_6}=\frac{53.0g}{180.156g/mole}=0.294moles

Now we have to calculate the moles of O_2.

The balanced chemical reaction will be,

C_6H_{12}O_6(aq)+6O_2(g)\rightarrow 6CO_2(g)+6H_2O(l)

From the balanced chemical reaction, we conclude that

As, 1 mole of C_6H_{12}O_6 react with 6 moles of O_2

So, 0.294 mole of C_6H_{12}O_6 react with 0.294\times 6=1.764 mole of O_2

Now we have to calculate the mass of O_2.

\text{Mass of }O_2=\text{Moles of }O_2\times \text{Molar mass of }O_2

\text{Mass of }O_2=(1.764mole)\times (32g/mole)=56.448g

Therefore, the mass of oxygen required are, 56.448 grams

Rasek [7]

Answer:

Explanation:

Significant figure implies number of digits that are to be considered. Some rules are required to be considered when writing a given expression to an expected significant figures.

So that:

1) 0.00004050 is 4 significant figures

2) 54.7000 is 6 significant figures

3) 1,000.09 is 6 significant figures

4) 0.039 is 2 significant figures
