Question

The average human requires 120.0 g of glucose (C6H12O6) per day. How many grams of CO2 (in the photosynthesis reaction) are required in order to produce this amount of glucose?

Answer 1

4 moles CO2 will be be required to produce 120g of glucose .

Hope it helps

Answer 2

Answer:

The mass of $CO_{2}$ required to produce $120g$ of glucose measured is $176g$.

Explanation:

Given,

The mass of glucose ($C_{6}H_{12}O_{6}$) = $120g$

The mass of $CO_{2}$ required to produce $120g$ of glucose =?

Now, the photosynthesis reaction:

• $6CO_{2} + 6H_{2}O \rightarrow C_{6}H_{12}O_{6} + 6O_{2}$

From the reaction, we can see that $6 moles$ of $CO_{2}$ required to produce $1mole$ of glucose.

As we know,

• The molar mass of glucose = $180g/mol$
• The molar mass of $CO_{2}$ = $44g/mol$
• The mass of $6$$CO_{2}$ = $6\times 44$ = $264g$

Thus,

• $180g$ of glucose required = $264g$ of $CO_{2}$
• $1g$ of glucose required = $\frac{264}{180}g$ of $CO_{2}$

Therefore,

• $120g$ of glucose required = $120\times \frac{264}{180}g$ of $CO_{2}$ = $176g$ of $CO_{2}$

Hence, the mass of $CO_{2}$ required to produce $120g$ of glucose = $176g$.
