Question

How many grams of hydrogen are contained in 2.00 mol of C6H7N

Answer 1

Answer:- 14.0 moles of hydrogen present in 2.00 moles of
`[tex]C_6H_7N` .

Solution:- We have been given with 2.00 moles of
`C_6H_7N` and asked to calculate the grams of hydrogen present in it. It's a two step conversion problem. In first step we convert the moles of the compound to moles of hydrogen as one mol of the compound contains 7 moles of hydrogen. In next step the moles are converted to grams on multiplying the moles by atomic mass of H. The calculations are shown as:

`2.00molC_6H_7N((7molH)/(1molC_6H_7N))((1.0gH)/(1molH))`

= 14.0 g H

So, there are 14.0 g of hydrogen in 2.00 moles of
`C_6H_7N` .
