Answer: 0.118M
Explanation:
The formula for molarity is: 
First, we need to find the number of moles of NaCl.
Next, we must convert millimeters to liters. We can do that by dividing the number of mL by 1000.
Now we have our needed data! All we need to do now is plug in our data to the molarity formula.
I hope this helps! Pls mark brainliest!! :)
We have to know how urbanization causes pollution.
The reason is: People in urban areas consume more energy, food, and water.
Urbanisation is one of the major problem towards pollution. The smoke from automobiles, factories and power generators make air unhealthy. Also chemical spills and other toxic gases contaminate in air.
The mixing of toxins in the soil is polluting soil which disturbs eco-system.
The high density population in urban area consume more energy , food and water which causes pollution.
You have molarity and you have volume. Use the formula :
Molarity(M)= Moles(N)/Liter(L) to get the solution.
150 ml= .150 L
7.7 = N/.150
N=.1.155 moles of NaOH.
And since you know the moles, use the molar mass to figure out the grams.
<span> (40g/mol NaOH) x (1.155mol) =
46.2 g of NaOH.</span>
Answer:
(C) The recrystallization solvent should be nonvolatile.
Explanation:
Recrystallization is the separation technique which is used to purify the solid compounds in their crystal or amorphous form.
Some properties follow the recrystallization process as:
The solids are more soluble in hot solvent as compared to the solubility in the cold solvent.
The solvent must have lower boiling point and can be volatile easily.
The solvent should not react with the compound.
The impurities must be soluble in the cool solvent, so that only the pure product crystallizes.
Hence, Answer - C which is not an ideal characteristic.
