Question

Can you walk me through the steps of solving my online homework please?

Answer 1

We want to consume 0.0424 moles of sucrose. We need to find the grams using the molar mass of sucrose which is 342 g/mol.

`0.0424\text{ moles sucrose}\cdot\frac{342\text{ g sucrose}}{1\text{ mol sucrose}}=14.5\text{ g sucrose.}`

With this data, we can do a rule of three to find the amount of cereal that contains 14.5 gr of sucrose, like this:

`\begin{gathered} 11\text{ gr sucrose }\to\text{ 60 gr cereal} \\ 14.5\text{ gr sucrose }\to?\text{ gr cereal} \end{gathered}`

And the calculation would be:

`14.5\text{ gr sucrose}\cdot\frac{60\text{ gr cereal}}{11\text{ gr sucrose}}=79.09\text{ gr cereal.}`

The answer is that we're going to eat 79 grams of cereal if we want to consume 0.0424 moles of sucrose.
