Calculate the molarity of a solution prepared by dissolving 1.495 moles of lioh in enough water to give a final volume of 750. m
zhenek [66]
Molarity can be defined as the number of moles of substance dissolved in 1 L of solution.
In the given question ,
number of LiOH moles - 1.495 mol
Dissolved volume - 750 mL
molarity is calculated for 1 L = 1000 mL
In 750 mL - 1.495 mol of LiOH is dissolved
Therefore in 1000 mL - 1.495 mol / 750 mL x 1000 = 1.99 mol

What is the oxidation number of phosphorus (P) in phosphoric acid (H3PO4)?
Sedaia [141]

Hey there!:

H is always +1 so the H's have a +3 charge.

O is always -2 so the O's have a -8 charge .

Now, suppose oxidation state for P = X , then :

+3  + X + (-8) = 0      (because of neutral molecule)

x = 8 - 3

x = + 5

So, X = +5 oxidation state.

Answer  C


Hope that helps!
