Answer:
The molarity of a solution is "25 M".
Explanation:
The given values are:
Moles of solute,
= 12.5 g
Volume of solution,
= 500 mL
i.e.,
= 0.5 L
Now,
The molarity will be:
=
On substituting the values, we get
=
=
3.8x10^-4 g is dissolved into 450g of water . Find the concentration in ppm
1 answer:
Answer:
0.84ppm
Explanation:
Mass of solute = 3.8 x 10⁻⁴g
Mass of solution = 450g
Unknown is the concentration in ppm; parts per million
The parts per million is one of the units of representing small concentration of solutes in a solution.
Solutes are the substances dissolving in another to give solution.
Here the concentration is expressed in a million units.
Concentration in ppm = x 10⁶
= x 10⁶
= 0.84ppm
