You make a solution that has 30 molecules of sugar, 5 molecules of salt and 65 molecules of water.
a. What is the sugar concentration (in %)? B. What is the total solute concentration (in %)? C. What is the water/solvent concentration (in %)?

a is the answer to this question

explanation:

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.
