A certain molecular compound has a solubility in hexane of at . Calculate the mass of that's dissolved in of a saturated solutio
Alex777 [14]

The question is incomplete. The complete question is:

A certain molecular compound M has a solubility in acetone of 0.737g/mL at 10.°C .Calculate the mass of M that's dissolved in 9.0 L of a saturated solution of M in acetone at this temperature.

Be sure your answer has the correct unit symbol and number of significant digits.

Answer: 6633 g of M is dissolved in 9.0 L of saturated solution in hexane at this temperature.

Explanation:

Given : 0.737g of solute is present in 1ml of solution

i.e 1ml of solution contains = 0.737 g of solute

Thus 9L or 9000ml of solution contains=\frac{0.737g}{1ml}\times 9000ml=6633g

Thus 6633 g of M is dissolved in 9.0 L of saturated solution in hexane at this temperature.

Which one of the following is a balanced equation?
ziro4ka [17]

Answer: OA is a balanced equation.

Explanation: For an equation to be balanced, the number of atoms and the total charge of each element in the reaction, of the product and reactant side must be the same.

Considering OA; 6 atoms of nitrogen is present in the reactant side. Shifting to the product side, 6 atoms of nitrogen is also present. Taking the other element in the reaction into account, the number of atoms of each element balances on both sides.

you are given mixtures containin gthe following compounds. Which compound in each pair could be separated by stirring the solid
ExtremeBDS [4]

Answer:

(A) NaOH and Ca(OH)2: Ca(OH)2

(B) MgCl2 and MgF2: MgF2

(C) Agl and KI: AgI

(D) NH4Cl and PbCl2: PbCl2

Explanation:

We need to see the solubility in water, at similar temperatures, for each compound and see which one is less soluble than the other:

NaOH: 1000 g/L (25 °C)

Ca(OH)2: 1.73 g/L (20 °C)

MgCl2: 54.3 g/100 mL (20 °C)

MgF2: 0.013 g/100 mL (20 °C)

Agl: 3×10−7g/100mL (20 °C)

KI: 140 g/100mL (20 °C)

NH4Cl: 383.0 g/L (25 °C)

PbCl2: 10.8 g/L (20 °C)

After the comparison made we can conclude that the less soluble, after saturation of water, will precipitate first.
