Answer:
Tube 2: 8.26 * 10^-3; Tube 4: 6.83 * 10^-5
Explanation:
In the serial dilutions for MIC test, the volume of nutrient broth in each tube should be equal: 5.0 mL. And the volume of agent in each dilution should also be similar: 0.5 mL.
The serial dilutions was as following:
- Tube 1: 0.5/5.5
- Tube 2: 0.5 mL of tube 1 was diluted with 5.0 mL broth. Then, the dilution of tube 2 is (1:11) * (1:11) = (0.5/5.5) * (0.5/5.5) = 1:121 = 8.26 * 10^-3
- Tube 3: We perform the similar calculation. Thus, the result is 1:1331 = 7.51 * 10^-4
- Tube 4: It is 1:14641 = 6.83 * 10^-5.
Answer: I believe the Answer is A
Explanation:
A chemical formula is defined as the symbolic representation of atoms present in a compound or molecule which also depicts the ratio in which the elements are combined to each other.
Chemical formula's for the given compounds are as follows.
- Magnesium carbonate -
- Dinitrogen monoxide -
- Sulfuric acid -
- Sodium acetate -
- Copper (II) hydroxide -
Answer:
See explanation below
Explanation:
In this case, we can assume that the temperature is the same in both conditions. Let's assume that the temperature is 25 °C.
If the temperature is constant we can use the Boyle's law to calculate the volume. This law is:
P₁V₁ = P₂V₂
You should note that this expression is only valid when you have a constant temperature.
Solving for V₂:
V₂ = P₁V₁ / P₂
So all we have to do is replace the given values:
V₂ = 0.05 * 4x10⁶ / 1
V₂ = 200,000 L
