Answer:
Under the equilibrium condition
Explanation:
according to the phase rule given by Willard Gibbs, under the condition where the equilibrium between the number of phases is not affected by the gravity, electricity magnetic force or by surface action and the system is under constant temperature, pressure and concentration then the degrees of freedom(F) is proportional to the concerntration (C) and the Phases(P) at equilibrium condition.
the expression is given as : F= C-P+2
The given question is incomplete. The complete question is:
Calculate the number of moles and the mass of the solute in each of the following solution: 100.0 mL of 3.8 × 10−5 M NaCN, the minimum lethal concentration of sodium cyanide in blood serum
Answer: The number of moles and the mass of the solute are 
and 
respectively
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in ml
n = moles of 
= 
Thus the number of moles and the mass of the solute are and respectively
The correct answer for this question is
20.2 g silver placed in 21.6 mL of water and 12.0 g silver placed in 21.6 mL of water.
15.2 g copper placed in 21.6 mL of water and 50.0 g copper placed in 23.4 mL of water.
11.2 g gold placed in 21.6 mL of water and 14.9 g gold placed in 23.4 mL of water.

Answer:
0.35 weight fraction is liquid Forsterite and 0.65 weight fraction is liquid Fayolite
Explanation:
The lever rule is typically used to calculate the weight fractions of phases in a binary equilibrium phase diagram. It is also used in the estimation of the fraction of solid and liquid phases for a specific binary composition and temperature condition existing between the solid and liquid lines. Therefore, using the Figure. 8.9 and the use of lever rule, the composition of the remaining liquid would be 0.35 weight fraction of liquid Forsterite and 0.65 weight fraction of liquid Fayolite.
