How many milliliters of 1.50 M magnesium sulfate soulution is required to supply 2.50 mole of this salt?
arsen [322]

Answer:

1670 ml

Explanation:

molarity x Volume (Liters) = moles => Volume (Liters) = moles/Molarity

Volume needed = 2.50mol/1.50M = 1.67 Liters = 1670 ml.

When you calculate apercent recovery you may find sometimes that it islarger than 100%. Assuming this is NOT due to errors assoc
Romashka-Z-Leto [24]

Answer:

Presence of impurities in the product.

Explanation:

Laboratory experience has shown that the percent yield obtained from a reaction may be greater than 100% if the product obtained from the reaction contains impurities that causes its mass to be greater than it actually would be if the product was pure.

A typical impurity that may be present in a product is the solvent used. This can be removed by evaporation of the solvent or by washing the product thoroughly.

Reaction of solid products with gases may also increase the percentage yield above 100%.

If 180 grams of potassium iodide is dissolved in 100 cm3 of water at 30oC, a(n) _______________ solution is formed.
olga nikolaevna [1]

Super saturated solution is formed.

<u>Explanation:</u>

Solubility is the property of any substance's capacity, that is the solute of the substance is dissolved in the given solvent to form the solution. We have three different types of solution, unsaturated, saturated and supersaturated solution.

  • Unsaturated solution is a solution with lesser amount of solute than its solubility at equilibrium.
  • Saturated solution is a solution with the maximum solute dissolved in the solvent.
  • Super saturated solution is a solution with more solute than it is required.

The solubility of KI at 30°C is 153 g / 100 ml. Here 180 g of KI in 100 ml of water at 30°C is given, which has more solute than required, so it is super saturated solution.
