Question

2) A solution made from 105 mL of isopropanol in 145 mL of water has what volumepercentage of isopropanol?

Answer 1

Answer

42% of isopropanol

Procedure

Assuming additive volumes, the percentage will be calculated as follows:

$\%\text{ volume}=(\frac{105\text{ mL isopropanol}}{105+145\text{ mL}})\times100\%=42\%$
