Question 3 (2 points)

Using the following equation how many grams of water you would get from 846 g of
glucose:
C6H12O6 + 602 + 6CO2 + 6H20 + energy
Your Answer:
Answer
units g)

Answer 1

Answer: The mass of water produced is 507.6 g

Step-by-step explanation:

The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:

`\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}` ......(1)

Given mass of glucose = 846 g

Molar mass of glucose = 180 g/mol

Plugging values in equation 1:

`\text{Moles of glucose}=(846g)/(180g/mol)=4.7 mol`

The given chemical equation follows:

`C_6H_(12)O_6+6O_2\rightarrow 6CO_2+6H_2O+energy`

By the stoichiometry of the reaction:

If 1 mole of glucose produces 6 moles of water

So, 4.7 moles of glucose will produce =
`(6)/(1)* 4.7=28.2mol` of water

Molar mass of water = 18 g/mol

Plugging values in equation 1:

`\text{Mass of water}=(28.2mol* 18g/mol)=507.6g`

Hence, the mass of water produced is 507.6 g
