A 46.2 mL,0.568 M calcium nitrate solution is mixed with 80.5mL of 1.396M calcium nitrate solution.Calculate tge concentration o

Ne4ueva [31]

Answer:

1.09 M

Explanation:

Let's define the equation that will be used to calculate the final concentration of the resultant calcium nitrate solution. In order to calculate it, we need to find the total number of moles of calcium nitrate and divide by the total volume of the resultant solution:

$c=\frac{n}{V}$

This equation firstly helps us find the number of moles of calcium nitrate. Multiplying molarity by volume will yield the moles. Adding the moles from the first component to the second component will provide us with the total number of moles of calcium nitrate:

$n_{Ca(NO_3)_2}=46.2 mL\cdot0.568 M+80.5 mL\cdot1.396 M=138.62 mmol$

Now, the total volume of this solution can be found by adding the volume values of each component:

$V_total=46.2 mL+80.5 mL=126.7 mL$

Finally, dividing the moles found by the total volume will yield the final molarity:

$c_{final}=\frac{138.62 mmol}{126.7 mL}= 1.09 M$

Carvone is a substance that occurs in two forms having different arrangements of the atoms but the same molecular formula (c10h1

Korvikt [17]

The molecular mass of Carvone is calculated as;

= 12 (C)₁₀ + 1.008 (H)₁₄ + 16 (O)

= 120 + 14.112 + 16

= 150.112

%age of Carbon;

= (120 ÷ 150.112) × 100

= 79.94 %

%age of Hydrogen;

= (14.112 ÷ 150.112) × 100

= 9.40 %

%age of Oxygen;

= (16 ÷ 150.112) × 100

= 10.65 %
