Question 16 (3 points) What is the molarity of a solution that contains 81.25 g of NH3 in 1500 mL of
solution?
Your
Answer

Hey there!

Molar mass NH₃ = 17.031 g/mol

Number of moles = mass of solute / molar mass

Number of moles = 81.25 / 17.031

Number of moles = 4.7707 moles of NH₃

Volume in liters of solution :

1500 mL / 1000 => 1.5 Liters

Therefore :

Molarity = number of moles / Volume in liters

Molarity = 4.7707 / 1.5

Molarity = 3.180 M

Hope this helps!

according to kinetic-molecular theory, the following would not be considered an ideal gas:

a gas at very low volumes, when gas particles are very close together

a gas at very low temperatures, when gas particles have very little kinetic energy a gas

a gas with highly polar molecules that have very strong intermolecular forces

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.
