Question

Determine the molarity of a solution formed by dissolving 4.83 moles of NaCl (M=58.44 g/mol) in enough water to yield 2.16L of solution. round to three sig figs. do not include units.

Answer 1

The molarity of a solution : 2.24

Further explanation

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

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

Where

M = Molarity

n = number of moles of solute

V = Volume of solution (L)

4.83 moles of NaCl in 2.16 L solution

n = 4.83

V = 2.16 L

Molarity :

`\tt M=(4.83)/(2.16)=2.2361\rightarrow 3~sig~figs=2.24`
