An aqueous solution of methyl alcohol (molar mass = 32.05 g/mol) is prepared by dissolving 15.0 ml of the alcohol (d = 0.792 g/ml) in 75.0 ml of water (1.00 g/ml).

a. calculate the mass % of the aqueous alcohol solution.
b. calculate the molarity of the aqueous alcohol solution.
c. if 5.0 ml of the solution (above) is diluted to a volume of 50.0 ml, what is the molarity (m) of the resulting dilute solution?

i think   the answer is c hope i'm right

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
