A Student in a Chemistry Laboratory Has Access to Two $10 \%$

question 22

Multiple Choice

A student in a chemistry laboratory has access to two acid solutions. The first solution is $10 \%$ acid and the second is $35 \%$ acid. (The percentages are by volume.) How many cubic centimeters of each should she mix together to obtain $150 \mathrm {~cm} ^ { 3 }$ of a $25 \%$ acid solution?

• A) \(60 \mathrm { cc } \text { of } 10 \% \text { solution and } 102 \mathrm { cc } \text { of } 35 \% \text { solution }\)
• B) \(50 \mathrm { cc } \text { of } 10 \% \text { solution and } 90 \mathrm { cc } \text { of } 35 \% \text { solution }\)
• C) \(90 \mathrm { cc } \text { of } 10 \% \text { solution and } 60 \mathrm { cc } \text { of } 35 \% \text { solution }\)
• D) \(60 \mathrm { cc } \text { of } 10 \% \text { solution and } 90 \mathrm { cc } \text { of } 35 \% \text { solution }\)
• E) \(60 \mathrm { cc } \text { of } 10 \% \text { solution and } 100 \mathrm { cc } \text { of } 35 \% \text { solution }\)
