Answer:

$\huge{ \boxed{ \: 2.5 \: moles}}$

Step-by-step explanation:

The number of moles of
CoNO_3 solution given its volume and concentration can be found by using the formula,

$c = (n)/(v) \\$

where

c is the concentration in M , mol/dm³ or mol/L

v is the volume in L or dm³

n is the number of moles

From the question.

v = 5 L

c = 0.5 M

Doing a change of subjects we have,

n = c * v

n = 0.5 * 5 = 2.5

We have the final answer as
