So since the number of red dots stays the same, we need to find the constant. The constant here is the number of moles of solute. To find the number of moles of solute, we take 0.6 liters and we multiply it by three molar. 0.6
liters times three moles of solute over liters. The L's cross out 0.6 times three. We get 1.8 moles of solution.
