Chapter 1: Q15P (page 22)

What is the formal concentration (expressed as mol/L=M) ofNaCI when 32.0gare dissolved in water and diluted to 0.500L?

Short Answer

Expert verified

The value of the formula concentration is 1.10mol/L

Step by step solution

01

Definition of formal concentration

When a material's concentration is measured as the number of moles of the substance contained in a litre of solution, it is called a formal concentration.

02

Given values

A molarity of some strong electrolyte is described as the F (formal concentration). We have 32.0 g of NaCl dissolved in water and diluted to0.500 in this scenario.

The given mass of =32.0g

The volume=0.500L

The molar mass 58.44g/mol

03

Find the value of concentration

Use the formula below to get the number of moles:

nNaCI=mN=32g58.44g/mol=0.547mol

Represent this number as a formal concentration of a solution mol/L=M:

c=nVsolution=0.547mol0.5L=1.10mol/L

Thus, the value of the formula concentration is 1.10mol/L.
