Density is weight by volume.
First. If you divide the weight by density you can find the volume
Second you must convert the ML in to Liters.
1L=1000ml
0.38214 Liters.
Hey there!:
Molarity of NaOH = 6 M or 6 mol/L
Volume of NaOH = 40 mL
Therefore , number of moles of NaOH:
40 mL =( 6 mol / 1000 mL)*40=
6/ 1000 * 40 => 0.24 moles of NaOH
Hope this helps!
Answer:
The answer is B.
Explanation:
They are the strongest type of inter-molecular force attractive forces that can act between atoms. This is why Vander Walls forces important.
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.
A Kilowatt is bigger than a Watt. A measure of 1,000 Watts of power.
