Two beakers each contain a sodium chloride solution with a concentration of 0.200 mol/dm3. Beaker 1 contains 100 cm3 of solution and beaker 2 contains 400 cm3 of solution. Which statement is correct?
Beaker 2 contains more solute in mol\text{mol}mol, and beaker 2 has the higher concentration.
Beaker 2 contains more solute in mol\text{mol}mol, and the two concentrations are the same.
The beakers contain the same amount of solute in mol\text{mol}mol, and the concentrations are the same.
Beaker 1 contains more solute in mol\text{mol}mol, and beaker 1 has the higher concentration.
