What is the molarity of a solution made by dissolving 50.0 g of HBr in enough water to
make 600. mL of solution?

1.06M

Explanation:

Given parameters:

Mass of HBr  = 50g

Volume of water  = 600mL

unknown:

Molarity of the solution = ?

Solution:

The molarity of a substance is the number of moles of solute in a volume of solution.

   Mathematically;

             Molarity  =

Since the number of moles is unknown, let us solve for it;

         Number of moles  =

               Molar mass of HBr  = 1 + 80  = 81g/mol

    Number of moles  =    = 0.64mole

Convert the volume to liters or dm³;  600mL  =  0.6L or 0.6 dm³

Input the parameters and solve;

            Molarity  =   = 1.06M

c) always accurate

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
