How many moles of LiCl are contained in 50.0 mL of 0.600 M solution?

Answers

Answer:

0.0300 moles LiCl

Explanation:

You can find the amount of moles using the molarity formula. The general structure looks like this:

Molar Concentration (M) = moles / volume (L)

You were given the molar concentration and volume in milliliters. Once you convert the volume to liters (by dividing by 1,000), substitute the values into the molarity formula. Then, you can simplify to find moles. The final answer should have 3 sig figs according to the given values.

50 mL / 1,000 = 0.0500 L

0.600 M = moles / 0.0500 L

(0.600 M) x (0.0500 L) = moles

0.0300 = moles

This may be because cats belong to the lion family, and they evolved to hunt their own prey.The fact that my cat has fast-growing nails that can be kept sharp is a physiological adaptation, which has helped cats scratch off predators and thus better their survival chances. In this case, the sharp nails are structural but the fast growth is physiological.
