1. What is the molar concentration of Cl- ions in a solution of 5 moles of MgCl_2 in 10 L of solution?

2. What volume of a 5.0 M NaOH solution is essential to prepare 100.0 mL of a 0.2 M solution?

3. What mass of water is produced when 0.1 moles of C_2H_6 is reacted through 0.1 moles of O_2?

C_2H_6 + 7/2 O_2 --> 2CO_2 + 3H_2O

Sexactly how occupational.

You are watching: What is the molar concentration of cl- ions in a solution


We can calculate the concentration of a solute in a solvent in regards to the unit molarity (M). It is defined as the number of moles of the solute present in 1 liter of the solution.
