Step 1

Molarity is defined as follows:

Molarity\text{ \lparen mol/L or M\rparen= }\frac{Number\text{ of moles}}{Volume\text{ of solution \lparen L\rparen}}=\text{ }\frac{n}{V(L)}

---------

Step 2

<em>Data provided: </em>

V(L) = 2.85 L (solution)

Molarity = 0.10 M or mol/L

---------

Step 3

<em>Procedure:</em>

Molarity = n/V(L)

Molarity x V(L) = n

0.10 mol/L x 2.85 L = n

0.29 moles = n

Answer: 0.29 moles of NaCl

How many moles of KNO3 are in 500 mL of 2. 0 M KNO3? mol KNO3.
8090 [49]

The moles can be defined as the mass of the substance with respect to molar mass. The moles of potassium nitrate is 1 mol.

<h3>How to calculate moles of a substance?</h3>

The moles of a compound can be calculated from:

\rm Moles=\dfrac{Mass}{Molar\;mass}

The molarity can be defined as the moles of solute in a liter of solution.

The molarity can be expressed as:

\rm Molarity=\dfrac{Moles\;\times\;1000}{Volume\;(mL)}

The molarity of potassium nitrate solution is 2 M, and the volume is 500 mL.

The moles of potassium nitrate is given as:

\rm 2\;M=\dfrac{Moles\;\times\;1000}{500\;mL}\\ Moles=\dfrac{2\;\times\;500}{1000}\;mol\\ Moles=1\;mol

The moles of potassium nitrate in 2 M, 500 mL solution are 1 mol.
