Brice Hinton · Answer 1

When we convert the given mass in grams and volume in liters to m/v percent, we recall that m/v percent is expressed as grams/100 milliliters. In this case the expression becomes (50 grams / 2500 L) * (0.1L/100ml), that is equal to 0.002 grams / 100 mL. Hence the the concentration is equal to 0.2 m/v percent.
