Question

What is the concentration of 49.9grams of Sodium Chloride in 1.50 liters of
water?*

Answer 1

The concentration : 0.569 M

Further explanation

Given

Mass of NaCl : 49.9 g

Volume = 1.5 L

Required

The concentration

Solution

mol NaCl :

= mass : MW

= 49.9 : 58.5

= 0.853

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}}}`

Input the value :

M = 0.853 mol : 1.5 L

M = 0.569
