A 5% solution of ethanol is diluted from 50ml to 75ml. What is the new weight /Volume percent?

I'm going to ume it is volume% since only volumes are given. A 5% solution means that there is 5%*50ml=2.5ml of ethanol in the original solution. After dilution that means that the concentration of ethanol is 2.5ml/75ml*100%=3.3%
