Answer 1

The mass of cocoa it contains is;

`m=43.5\text{ grams}`

Step-by-step explanation:

Given that Kaitlin's chocolate bar is 63% cocoa.

If the weight of the chocolate bar is 69grams

The amount in grams of cocoa it contains is;

`\begin{gathered} m=63\text{\% of 69 grams} \\ m=0.63*69\text{ grams} \\ m=43.47 \\ m=43.5\text{ grams} \end{gathered}`

Therefore, the mass of cocoa it contains is;

`m=43.5\text{ grams}`
