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 :
[tex]\text{Mass}\%=\dfrac{\text{Mass of solute}}{\text{Mass of solution}}\times 100\\\\=\dfrac{8}{100}\times 100\\\\=8\%[/tex]
So, the percent by mass is 8%.
The percent by mass of the given copper in the alloy formed is 8%.
The given parameters;
The percent by mass of the given copper in the alloy formed is calculated as follows;
percent by mass of zinc = [tex]\frac{mass \ of \ zinc}{mass \ of \ the \ alloy} \times 100\%[/tex]
percent by mass of zinc = [tex]\frac{8}{100} \times 100\%[/tex]
percent by mass of zinc = 8%
Thus, the percent by mass of the given copper in the alloy formed is 8%.
