The correct answer is option 2. One
way of expressing concentration is by expressing it by parts per million or
ppm. It <span>is calculated by dividing the grams of solute and the grams of the solution, and the result is multiplied by 1 000 000. </span><span>Parts per million is equal to 1 milligram of solute per kilogram of
solution. </span>
According to Avogadro constant 1 mole = 6.02 x 10^23 what about 9.25 x10 ^21
that is 1 mole x ( 9.25 x10 ^21) / (6.02 x10^23) = 0.0154 moles
<span>In chemistry, the law of definite proportions, sometimes called Proust's law or the law of definite composition, or law of constant composition states that a given chemical compound always contains its component elements in fixed ratio and does not depend on its source and method of preparation. An equivalent statement is the law of constant composition, which states that all samples of a given chemical compound have the same elemental composition by mass.</span>
