PEEAASEEE HELLPP!! What is the molarity of 150 g C6H12O6 per 0.50 L?

A. 300 mol/L
B. 75.0 mol/L
C. 1.68 mol/L
D. 0.833 mol/L

The correct option is C) 1.68 mol/L

Explanation:

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:

.....(1)

Given values:

Given mass of = 150 g

Molar mass of = 180 g/mol

Volume of the solution = 0.50 L

Putting values in equation 1, we get:

Hence, the correct option is C) 1.68 mol/L

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

have a great day because if you dont you and i will be sad
