Equation: C1V1=C2V2
Given:
C1= 15 mM
V1=?
C2= 0.25 mM
V2= 1mL (Do I just plug 1mL into the equation or do I have to convert to liter? Does mM mean mmol/1L?)
I got ~17 microliter. Note: I must convert my answer to microliter.
Nope.
V1=C2V2/C1
= .25MilliMoles/liter*.001Liter/.15millimoles/liter
= .25/.15 * .001L
= 17*.001L= 17 milliLiters
I don't have a clue why you are coming up with microliters. little m means milli
So if wou need to convert to microliters, it is 17,000
To solve the equation C1V1 = C2V2, you need to determine the value of V1. Here's the process to find the value:
1. Given values:
- C1 = 15 mM
- V1 = ?
- C2 = 0.25 mM
- V2 = 1 mL
2. The units of concentration (C) are millimolar (mM), which means the concentration is given in millimoles per liter (mmol/L). The units of volume (V) are milliliter (mL).
3. Since volume is given in mL, you should convert the concentrations to millimoles per milliliter (mmol/mL) to maintain consistent units.
4. To convert mM to mmol/mL, divide the concentration by 1000 (since 1 L = 1000 mL). So, 15 mM = 15 mmol/L = 15 mmol/1000 mL = 0.015 mmol/mL.
5. Now, you can rewrite the equation with the converted units as follows:
0.015 mmol/mL * V1 = 0.25 mmol/mL * 1 mL
6. To isolate V1, divide both sides of the equation by 0.015 mmol/mL:
V1 = (0.25 mmol/mL * 1 mL) / 0.015 mmol/mL
7. Calculate the right side of the equation:
V1 = (0.25 mmol * 1) / 0.015 mmol = 16.67 mL
8. You obtained the result in milliliters (mL). To convert it to microliters (µL), multiply by 1000 since 1 mL = 1000 µL:
V1 = 16.67 mL * 1000 = 16670 µL
9. So, the value of V1 is approximately 16670 µL.
Please note that your stated answer of ~17 µL is incorrect. The correct answer is approximately 16670 µL (or 16.67 mL).
