Question

How many moles of hydrogen H are in 1.4738 g of sucrose C12H22O11

Answer 1

`0.095\text{ mole}`

Step-by-step explanation:

Here, we want to know the number of moles of hydrogen in the given mass of sucrose

To get this, we need to get the actual mass of the total that is hydrogen

Mathematically, we have that as:

`\begin{gathered} \frac{22(1)}{12(12)\text{ + 22(1)+11(16)}}\text{ = 0.064327 or 6.4327\%} \\ \text{where :} \\ 1\text{ is the atomic mass unit of hydrogen} \\ 12\text{ is the atomic mass unit of carbon} \\ 16\text{ is the atomic mass unit of oxygen} \end{gathered}`

Thus, we have the mass of hydrogen in the sucrose as:

`0.064327*1.4738\text{ = }0.095\text{ g}`

1 mole of hydrogen has a mass of 1g

x mole will have a mass of 0.095g

Thus,

`x\text{ = }(0.095*1)/(1)\text{ = 0.095 mole}`
