Alkenes are a type of unsaturated hydrocarbons which means they have a double bond in their structure, or lack maximum number of hydrogen atoms on each carbon.
Alkenes have a general formula of CnH2n. They are called unsaturated hydrocarbons since they have a double bond. They are therefore less stable compared to alkanes and also are readily reactive.

Ierofanga [76]

Answer:

50.76 mol H2O.

Explanation:

The photosynthesis follows the equation:

6CO2 + 6H2O ---> C6H12O6 + 6O2

This means that 6 mol of H2O are needed to obtain 1 mol of C6H12O6 (see the numbers that precedes every molecule to know how many mols are in game).

So we can say that:

1 mol C6H12O6 --------- 6 mol H2O

8.46 mol C6H12O6 -----x= 8.46 x 6 : 1 = 50.76 mol H20
