Question

What is the percent by mass of 8.0g copper is added yo enough zinc to produce 100g an alloy brainly

Answer 1

Answer:

8%

Explanation:

Given that,

Mass of solute = 8 g

Mass of soultion, (mass of alloy) = 100 g

We need to find the percent by mass of 8.0g copper is added to enough zinc to produce 100g an alloy. It can be calculated by the formula as follows :

$\text{Mass}\%=\dfrac{\text{Mass of solute}}{\text{Mass of solution}}\times 100\\\\=\dfrac{8}{100}\times 100\\\\=8\%$

So, the percent by mass is 8%.
