How many grams of glucose are in 175 mL of a 5.50% (m/v) glucose solution?

1. 5.50% m/v means that the solution contains 5.50% of the volume measured in grams

so in 165mL you will have 5.5%*165 = 9.075g

2. 18.5% v/v means 18.5% of the total volume is methyl alcohol

so in 1.87L you will have 18.5%*1.87 = 0.35L of methyl alcohol.

3. This one works backwards. If 32.1 g is 6.00%, what is 100%?

100% = 32.1/0.06 = 535 mL
