A student has 0.75 L of a 5.0 M solution and dilutes it to make 3.5 liters. What’s the molarity of the diluted solution?
Marianna [84]

The molarity of the diluted solution : 1.1 M

<h3>Further explanation</h3>

Dilution is the process of adding solvent to get a more dilute solution.

The moles(n) before and after dilution are the same.

Can be formulated :

\tt n_1=n_2\\\\M_1.V_1=M_2.V_2

M₁ = Molarity of the solution before dilution  

V₁ = volume of the solution before dilution  

M₂ = Molarity of the solution after dilution  

V₂ = Molarity volume of the solution after dilution

M₁=5

V₁=0.75

V₂=3.5

\tt M_2=\dfrac{M_1.V_1}{V_2}\\\\M_2=\dfrac{5\times 0.75}{3.5}\\\\M_2=1.07\approx 1.1

Inga [223]

Answer:

1085° C

Explanation:

From the phase diagram of Ag-Cu shown below:

The minimum value of the high-temp required to be selected for the furnace is: 1085° C

This is on the grounds that the furnace should be chosen to such an extent that it should melt any sort of possible material including pure Cu that melts and liquefies at the temperature of 1085° C.
