Given that the molar mass of NaNO3 is 85.00 g/mol, what mass of NaNO3 is needed to make 4.50 L of a 1.50 M NaNO3 solution? Use m
Virty [35]

<u>Ans: Mass of NaNO3 = 574 g</u>

<u>Given:</u>

Volume of NaNO3, V = 4.50 L

Molarity of NaNO3, M = 1.50 M i.e. 1.50 moles/L

Molar mass of NaNO3 = 85.00 g/mol

<u>To determine:</u>

The mass of NaNO3

<u>Explanation:</u>

Molarity of a solution can be expressed as the number of moles of the solute in a liter volume of solution

Molarity  of NaNO3 = moles of NaNO3/volume of solution in L

1.50 moles/L = moles/4.50 L

moles NaNO3 = 1.50 *4.50 = 6.75 moles

Now, moles of NaNO3 = mass of NaNO3/molar mass NaNO3

mass of NaNO3 = moles * molar mass =

                          = 6.75 moles * 85.00 g/mole

                          = 573.75 g = 574 g

Which surface has the most friction
Nesterboy [21]

Answer: Rougher surfaces have more friction between them than smoother surfaces. That's why we put sand on icy sidewalks and roads. You can't slide as far across ice with shoes as you can on the blades of skates. The rougher surface of the soles of the shoes causes more friction and slows you down.<em> There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest.</em>

Hope this helps
