Find the percentage by weight and weight...

Find the percentage by weight and weight fraction of aspirin in the solution prepared by dissolving `3.65 g` of aspirin in `25.08 g` of water.

Text Solution

Verified by Experts

weight of solution `= 3.65 +25.08 = 28.73 g`
weight fraction `= (3.65)/(28.73) = 0.127`
weight percent `= 0.127 xx 100 = 12.7%`
