In lab this week you'll be using a new unit for for concentration, the mass ratio. Let's walk through a mass ratio calculation. Assume we combine 10mL of 2% mass/volume cornstarch ( 2g of cornstarch per 100mL ) with 5 mL of a 1% mass/volume guar gum solution ( 1g of guar gum per 100mL ). We have grams of cornstarch and grams of guar gum in this solution. Using the equation above, we calculate the mass ratio of guar gum in the mixed solution as Then, the mass ratio of cornstarch in the mixed solution is In lab this week you'll be using a new unit for for concentration, the mass ratio.
