Answer:
Yes
Explanation:
Sulfur in its pure do not have any taste and odor but many foods rich in sulfur can have a distinct odor and taste. The foods contains sulfur in very small amounts but some of the foods which are known for rich in sulfur are onion, garlic, egg, flex seeds, walnuts, meat, red bell pepper, cheese, green vegetables etc.
The foods rich in sulfur helps in fighting skin acne and fights skin infection which makes our skin brighter because of this property of sulfur it is used in skin antiseptic creme and medicines.
The intake of the excess sulfur can cause burning sensation, diarrhea, tonsils and even can cause brain damage if taken in too excess and death of the brain cells. So, the sulfur is good for health and is a remedy for our skin if taken by the natural source of food in a healthy amount.
1.66 M is the concentration of the chemist's working solution.
<h3>What is molarity?</h3>
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.
In this case, we have a solution of Zn(NO₃)₂.
The chemist wants to prepare a dilute solution of this reactant.
The stock solution of the nitrate has a concentration of 4.93 M, and he wants to prepare 620 mL of a more dilute concentration of the same solution. He adds 210 mL of the stock and completes it with water until it reaches 620 mL.
We want to know the concentration of this diluted solution.
As we are working with the same solution, we can assume that the moles of the stock solution will be conserved in the diluted solution so:
= 
(1)
and we also know that:
n = M x 
If we replace this expression in (1) we have:
x 
= 
x
Where 1, would be the stock solution and 2, the solution we want to prepare.
So, we already know the concentration and volume used of the stock solution and the desired volume of the diluted one, therefore, all we have to do is replace the given data in (2) and solve for the concentration which is :
4.93 x 210 = 620 x
= 1.66 M
This is the concentration of the solution prepared.
