Answer:

remember, the number of atoms is represented by the subscript. if there is a coefficient, multiply it by the subscript. if there is no subscript or coefficient written, assume it is 1.

cu = 1 atom on the reactants side, 1 atom on the products side

s = 1 atom on the reactants side, 1 atom on the products side

O = 2 atoms on the reactants side, 2 atoms on the products side

What is molarity of a solution containing 0.34 moles of FeCl3 in the 0.45 liters of water

Minchanka [31]

Hello!

Molarity is defined as the number of moles of a substance that can be found in 1 liter of solution. That is expressed mathematically as M=mol/L

For the FeCl₃ solution:

$M= \frac{mol FeCl_3}{L sol}= \frac{0,34 moles FeCl_3}{0,45 L}= 0,756 M$

So, the concentration of this solution is 0,756 M
