What is primarily responsible for holding two nitrogen atoms together in a molecule of nitrogen gas?
kotykmax [81]

The answer is B Nitrogen atoms will form three covalent bonds (also called triple covalent) between two atoms of nitrogen because each nitrogen atom needs three electrons to fill its outermost shell. Another example of a nonpolar covalent bond is found in the methane (CH4) molecule.

What is the molarity of 200. mL of solution containing 4.50 moles of ZnCl2?
MariettaO [177]

Answer:

Molarity of solution = 0.9 M

Explanation:

Given data:

Moles of ZnCl₂ = 4.50 mol

Volume of solution = 200 mL

Molarity of solution = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

Now we will convert the volume in L.

200 mL×1 L/1000 mL = 0.2L

M = 4.50 mol / 0.2 L

M = 0.9 M
