Lithium hydroxide is used in alkaline batteries. Calculate the molarity of a solution prepared by dissolving 1.495 moles of LiOH in enough water to give a final volume of 750. mL. 1) 1.99 M
2) 1.50 M
3) 1.12 M
4) 0.502 M
5) 0.00199

1)1.99 M

Explanation:

Molarity  is given as = moles solute/Liter solution

The solute which is LiOH is already given in moles as 1.495 moles

Given that solution  is  750 mL,  we convert to liters.

Liters of the solution=  mL of the solution   x (1 L/1000 mL)

750 mL x (1 L/1000 mL)

0.75 L

Molarity = moles solute/Liter solution

Molarity = 1.495 moles of LiOH/0.75 L of solution

Molarity = 1.99M

The molarity of this solution is 1.99M (moles per liter).

most sediment washes or falls into the river as a result of mass movement and runoff. other sediment eroded from the bottom or sides of the river.

a is the answer

explanation:

which statement about trans-fatty acids is false?

a. the conversion of cis-fatty acids to trans-fatty acids is inhibited by the presence of antioxidants.

hope this
