Explain why the molar ratio is needed to determine the theoretical mass ratios.
choli [55]

Answer:

The overview of the subject is outlined underneath in the summary tab.

Explanation:

  • The molar ratio seems to be essentially a balanced chemical equilibrium coefficient that implies or serves as a conversion factor for the product-related reactants.
  • This ratio just says the reactant proportion which reacts, but not the exact quantity of the reacting product. Consequently, the molar ratio should only be used to provide theoretical instead of just a definite mass ratio.

A 125 mL aqueous solution contains 1.86 mc032-1.jpg 10–5 g of potassium chloride and has a density of 1.02 g/mL. What is the con
Elan Coil [88]
Mass of the <span>solvent (H2O) in kg

D = m / V

1.02 = m / 125

m = 1.02 x 125

m = 127.5 g of H2O

127.5 / 1000 => 0.1275 kg

mass of  solute in mg:

1000 x  ( 1.86 x 10</span>⁻⁵ ) = 0.0186 mg
<span>
ppm = mass of solute in mg / mass of solvent in kg

ppm = 0.0186 / </span><span>0.1275
</span><span>
= 0.1458 ppm

hope this helps!
