Question 341817
Juan mixes 25 mL of a 15% acid solution with 60 mL of a 25% acid solution and 48 mL of a 50% acid solution. About what percent acid is the final solution?
25ml 15%
60 ml 25%
48 ml 50%
Let percent in thefinal solution be x
and quantity will be 133 ml
25*15+60*25+48*50=133*x
375+1500+2400=133x

4275 =133x
x= 424/133
x= 32.14%
