Question

How many moles are in 5. 000 L of a 0. 5 M solution of CoNO3

Answer 1

`\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

2.5 moles
