If 1.8 L of water is added to 2.5 L of a 7.0 M KOH solution, what is the molarity of the new solution?

Molarity= (number of moles of that substance) / (Volume of solution in litres)

7= (number of moles of HCl) / 0.05

Thus,

Number of moles of HCl = 7 x 0.05 = 0.35

The number of moles of HCl will remain unchanged.

Now, for new solution,

0.35= 0.35 / (New volume of solution in litres)

Thus,

New volume = 1 litre

Thus, amount of water added = 1- 0.05 litre = 5.0 M

Answer:
            The name of given molecule is 3-Methylpent-2-ene.

Explanation:
                   First of all a carbon chain of five carbons was drawn. Then a double bond was made between carbon 3 and 4 (starting from left). A methyl group was drawn at middle carbon which is at position 3.

                    Molecule sketched was named as,

1) A longest chain containing double bond was selected and numbering was started from the end closest to double bond. Hence, 

                                  2-Pentene or Pent-2-ene

2) The position of substituent was specified before the parent name, Hence,

                       3-Methyl-2-Pentene or 3-Methylpent-2-ene

Dissolving 16 g of urea (MW= 60 g/mol) in 39 g of water produces 42.3 ml of solution. Determine the molarity of this solution
Genrish500 [490]

Hey there!:

Molar mass urea = 60 g/mol

Number of moles of solute:

moles solute = mass solute / molar mass

moles solute = 16 / 60

moles solute => 0.2666 moles of urea

Volume in liters:

42.3 mL / 1000 => 0.0423 L

Therefore:

Molarity = moles of solute / volume of solution

Molarity = 0.2666 / 0.0423

= 6.302 M


Hope that helps!
