Question

find moles of sucrose (c12 h22 o11) which contain 11 mole hydogen atom?

Answer 1

Answer : The number of hydrogen atoms present in 25.6 g of sucrose is,  

Explanation : Given,

Mass of sucrose = 25.6 g

Atomic mass of sucrose = 342.3 g /mole

First we have to calculate the moles of sucrose.

As we know that the there are 12 number of carbon atoms, 22 number of hydrogen atoms and 11 number of oxygen atoms.

Now we have to calculate the number of hydrogen atoms present in sucrose.

As, 1 mole contains number of hydrogen atoms

So, 0.075 mole contains number of hydrogen atoms

Therefore, the number of hydrogen atoms present in 25.6 g of sucrose is,
