1.) What is the volume of a 20% methyl solution that contains 15 ml of methyl?
2.) What is the percent by mass concentration of a solution that contains 30.0 g of sugar dissolved in 150 g of water?
[tex]\huge \bold \blue{ANSWER:}[/tex]
=================================
[tex]1.) \: 3 [/tex]
Solution:
15 x 20% = 3
=================================
[tex]2.) \: 16.67% [/tex]
Solution:
Total mass = 30g sugar + 150g water
Total mass = 180g
Now, you can find the mass percentage of sugar using the formula:
Mass percent = (grams of solute / grams of solution) x 100
Mass percent = (30g sugar/ 180g solution) x 100
Mass percent = (0.1666666667) x 100
Answer = 16.67% sugar
