Question

What is the molarity of 2.0 L of solution in which 4.0 moles of sodium bromide (NaBr) is dissolved?

Answer 1

The molarity of the solution is 2.0 M. The molarity of a solution is defined as the number of moles of solute per liter of solution. In this case, we have 4.0 moles of sodium bromide (NaBr) dissolved in 2.0 liters of solution. To calculate the molarity, we can use the formula: Molarity (M) = Moles of Solute / Volume of Solution (in liters).

Step-by-step explanation:

The molarity of a solution is defined as the number of moles of solute per liter of solution. In this case, we have 4.0 moles of sodium bromide (NaBr) dissolved in 2.0 liters of solution. To calculate the molarity, we can use the formula:

Molarity (M) = Moles of Solute / Volume of Solution (in liters)
Substituting the given values, we get:

Molarity (M) = 4.0 moles / 2.0 liters = 2.0 M.

The molarity of the solution is 2.0 M. The molarity of a solution is defined as the number of moles of solute per liter of solution. In this case, we have 4.0 moles of sodium bromide (NaBr) dissolved in 2.0 liters of solution the molarity, we use the formula: Molarity (M) = Moles of Solute / Volume of Solution (in liters).
