A block of metal has a mass of 51.11 g and displaces 71.46 ml of water. Calculate the density of the metal in g/ml.
Damm [24]

Answer:

The answer is

<h2>0.07 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass of metal = 5.11 g

volume = 71.46 mL

The density of the metal is

density =  \frac{5.11}{71.46}  \\  = 0.071508536...

We have the final answer as

<h3>0.07 g/mL</h3>

Hope this helps you

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.
