Asolution has a volume of 2.0 l and contains 36.0 g of glucose. if the molar mass of glucose is 180 g/mol, what is the molarity of the solution?

- Molarity of the glucose solution is 0.1M.

Solution:- Molarity is moles of solute per liter of the solution.

From given info, 36.0 grams of glucose are present in a 2.0 L solution. We need to convert the grams to moles using molar mass and then divide the moles by the liters to get the molarity.

First step, grams to moles conversion:

= 0.2 mol

Second step, calculations for molarity:

molarity =

= 0.1M

(where, M stands for molarity)

So, the molarity of the glucose solution is 0.1M.

explanation:

"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."
