And if you pour that dilute solution into another glass of water, it becomes weaker still.

如果你再往已稀释的威士忌中倒进一杯水，威士忌会变得更淡。

M2 and V2 are the molarity and volume of the dilute solution.

M2 和 V2 是稀溶液的摩尔浓度和体积。

Add water to dilute the solution to the required strength.

【strength】加水稀释溶液使其达到要求的浓度。

And we discovered how to calculate a solution's molarity, as well as how to dilute a solution using the dilution equation.

我们还发现了如何计算溶液的摩尔浓度， 以及如何使用稀释方程来稀释溶液。

Again, it is the movement from a dilute solution, so high concentration of water molecules down the concentration gradient to a more concentrated solution, so low concentration of water molecules.

同样，它是从稀溶液（水分子浓度高）沿着浓度梯度向下移动到更浓的溶液（水分子浓度低）。
