Question

Find the molarity of a mixed solution formed by adding 350ml of 0.2M NaOH to 200ml of 0.5M NaOH solution
,
​

Answer 1

Answer:

Answer:

Well, by definition,

molarity

=

moles of solute

volume of solution

Explanation:

Now the

moles of solute

are a constant. The volume of solution MAY change substantially with increasing or decreasing temperature. In some calculations

molality

is used in preference, which is defined by the quotient....

molality

=

moles of solute

kilograms of solvent

....this is temperature independent, and at lower concentrations,

molarity

≡

molality

Answer 2

Answer:

0.30

Explanation:

m1v1+m2v2=m3v3

0.2×350+0.5×200=550×m3. (350+200=550)

70+100=550×m3

170/550= M3

0.30 = m3
