Ludmilka [50]2 years ago
8 0

The molarity = 0.454 M

<h3>Further solution</h3>

Given

Volume = 3 L of solution

mass = 140 g of NaBr

Required

The molarity

Solution

Molarity is a way to express the concentration of the solution

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}

mol of NaBr :

= mass : MW

= 140 g : 102,894 g/mol

= 1.361

Molarity :

= 1.361 mol : 3 L

= 0.454 M
