When a 1.00 L sample of water from the surface of the Dead Sea (which is more than 400 meters below sea level and much saltier than ordinary seawater) is evaporated, 186 grams of MgCl2 are recovered. What is the molarity of MgCl2 in the original sample? M

Molarity of in the original sample was 1.96M

Explanation:

Molarity is defined as the number of moles of solute dissolved per liter of the solution.

Now put all the given values in the formula of molarity, we get

Thus molarity of in the original sample was 1.96M

201cm/s÷5: 18

explanation:

there is no explanation

the product of the pressure and volume is also constant
