Question

A cereal contains 11.0 grams of sucrose(C₁₂H₂₂O₁₁) per 60.0 grams of cereal. What mass in grams of cereal must be eaten to consume a total of 0.0424 moles of sucrose?

Answer 1

I have recorded a video above with the work through on this one. I hope it helps!

Answer 2

Convert 0.0424 moles sucrose to grams of sucrose:

molar mass sucrose = 342.30 g / mole

0.0424 moles x 342.30 g / mole = 14.51 g sucrose

Next, determine grams of cereal needed to contain 14.51 g of sucrose:

14.51 g sucrose x 60.0 g cereal / 11.0 g sucrose = 79.2 g cereal needed

...or done another way:

you have 11.0 g / 60.0 g cereal = 0.183 g sucrose / g cereal

14.5 g / 0.183 g = 79.2 g cereal
