Question

You have two solutions of chemical A. To determine which has the highest concentration of A (molarity), which of the following must you know (there may be more than one answer)?a. the mass in grams of A in each solutionb. the molar mass of Ac. the volume of water added to each solutiond. the total volume of the solution

Answer 1

a, b and c

Step-by-step explanation:

To calculate molarity the number of moles and volume in dm3 is needed. So with the mass and molar mass the number of moles can be gotten and hence the molarity when dividing the number of moles by the volume in dm3.
