The concentration in mol/L of the chemist's potassium iodide solution : = 4.4 x 10⁻⁴ M
<h3>Further explanation</h3>Given
88. μmol of Potassium iodide
200. mL volumetric flask
Required
The concentration
Solution
Molarity is a way to express the concentration of the solution
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
Conversion :
88. μmol = 88 . 10⁺⁶ mol = 8.8 10⁻⁵ mol
200 ml = 0.2 L
The molarity :
= n : V
= 8.8.10⁻⁵ : 0.2
= 4.4 x 10⁻⁴ M
So let's use some equations to represent the data [let R= cost of ring & B= cost of bracelet]
R= B + $ 36 .... (1)
B=
× R ... (2)
By using simultaneous equations to solve for B and R.
Substitute eq. (1) into eq. (2)
B = × (B + $36)
B =B + 
⇒ B = $48
By substituting value of B into ea (1)
If R = B + $36
R = ($48) + $36
= $84
∴ <span> the total of the two items = R + B
= $84 + $48
</span> = $132
R= B + $ 36 .... (1)
B=
