What statement best describes solution

Solution is a mixture of solvent and solute. Which dissove completely.

Examples of Solvent - Water

                     Solute - Salt

                     Solution - Salt solution

Together when the combines, it became a solution

*** It have to dissolve completely. Particles cannot be left in the cup(container). The only way to seprate them is to use EVAPORATION METHOD.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
