Question

Please hurry and tell the answer to:

If a 20.0 g sample of sucrose (table sugar) has 1.30 g of Hydrogen, what would be the expected mass of Hydrogen in a 100.0g sample of sucrose?

Answer 1

6.50 g of Hydrogen

Step-by-step explanation:

We know that in every 20.0g of sucrose, there are 1.30g of hydrogen.

We now have 100.0g of sucrose. 100.0g is 5x larger than the 20.0g sample, which is a 5 : 1 ratio. Applying this ratio to the amount of hydrogen, we would have 5*1.3g of hydrogen in the 100.0g of sucrose.

5*1.3 = 6.5, so our answer is that there are 6.50g of hydrogen in 100.0g of sucrose.

Hope this helps!
