Question

What size volumetric flask would you use to create 1.50 M solution using 43.85 g of nacl​

Answer 1

0.5L = 500mL

Step-by-step explanation:

Molarity of a solution is given by;

M= n/V

Where;

n= number of moles of solute

V= volume of solution = size volumetric flask

n=m/m.m

Where; m= mass of solute=43.85g

m.m= molar mass of solute=58.5g

Note that solute is NaCl(s)

n=43.85/58.5=0.75mol

We are that the molarity is 1.50M

To find the size of the volumetric flask, we make V in M=n/V subject of formula

V=n/M

V=0.75/1.50

V=0.5

Therefore, the size of volumetric flask is 0.5L = 500mL
