There will be needed 982.35 mL of solution to obtain 16.1 grams of the salt.There will be needed mL of
Why?
In order to calculate how many milliliters are needed to obtain 16.1 grams of the salt given its concentration, we first need to find its chemical formula which is the following:
Now that we know the chemical formula of the substance, we need to find its molecular mass. We can do it by the following way:
We have that the molecular mass of the substance will be:
Therefore, knowing the molecular mass of the substance, we need to calculate how many mols represents 16.1 grams of the same substance, we can do it by the following way:
Finally, if we need to calculate how many milliliters are needed, we need to use the following formula:
Now, substituting and calculating, we have:
Henc, there will be needed 982.35 mL of solution to obtain 16.1 grams of the salt.
Have a nice day!
Answer:
N,N-dimethylacetamide is formed.
Explanation:
- It is an example of a nucleophilic addition-elimination reaction. Here dimethylamine acts as a nucleophile.
- In the first step, dimethyl amine gives nucleophilic addition reaction at carbonyl center of acetyl chloride.
- In the second step, removal of Cl atoms occurs.
- In the third step, deprotonation takes place from amino group to produce N,N-dimethylacetamide.
- Full reaction mechanism has been shown below.
Answer:
cold
Warm air lifted over a moving cold air mass will produce a _____ front.
Oxygen,carbon,hydrogen,and nitrogen- together make up 95 percent of the mass of the human body.
Hope this helps.
Answer: A
Explanation:
The buoyancy force only takes affect when an object is placed in water and floats. This occurs because the density of that object is less than the density of water.
Water is the main liquid used for measuring the density of an object.
Hope this helps! Please tell me if I am wrong :3
