Answer:
200 g/L
Explanation:
The concentration of a solution (also called molarity) can be calculated with the formula:
where
m is the mass of the solute
V is the volume of the solution
For the solution in this problem we have:
m = 50g is the mass of the solute
V = 250 mL = 0.250 L is the volume of the solution
Therefore, the concentration of the solution is:
Answer:
The degree of unsaturation for a compound with molecular formula C₆H₆ is 4.
Explanation:
The degree of unsaturation is calculated through the following formula:
2n + 2 - H / 2
n = Total number of hydrogen in given compound
There are six hydrogen in given compound, now we will calculate the degree of unsaturation by putting the value of n= 6
(2(6) + 2 - 6 )/ 2
(12+ 2 - 6) / 2
(14 - 6) /2
8 / 2 = 4
The degree of unsaturation for a compound with molecular formula C₆H₆ is 4.
The given compound is benzene and degree of unsaturation is 4. Three double bond and one ring.
I believe you should have attached the photo indicated in
the problem. Nevertheless this problem can still be solved without the photo.
When I think about a sulphide mineral and which forms a
cube shaped crystal, the answer to this question must be Pyrite.
