Question

A laboratory experiment requires 4.8 L of a 2.5 M solution of sulfuric acid (H2SO4), but the only available H2SO4 is a 6.0 M stock solution. How could you prepare the solution needed for the lab experiment? Show all the work used to find your answer.

Answer 3

@mayankdevnani can u plz help?

Answer 4

From this whole question,we can conclude that moles are same when we dilute and un-dilute acid.

Answer 5

correct or not ?

Answer 6

yes, correct!

Answer 7

\(\sf \huge M_1V_1=M_2V_2\)

Answer 8

so,we get
\[ \bf Molarity~diluted \times volume~diluted=given~molarity \times given~volume\]

Answer 9

u just copied and pasted that from yahoo answers @Nurali

Answer 10

understood or not? @iamabarbiegirl

Answer 11

just abhisar write it in short form

Answer 12

oh ok

Answer 13

\(\sf 4.8\times 2.5=6\times V\)
Now find the value of V

Answer 14

then plug values,we get
\[\large \bf 2.5 \times 4.8=6.0 \times x(volume)\]
now solve for x

Answer 15

LOL !
yes

Answer 16

we divide both sidea by 6? @Abhisar

Answer 17

yeah and then simplify it

Answer 18

\(\color{blue}{\text{Originally Posted by}}\) @Abhisar
\(\sf \huge \frac{(4.8\times 2.5)}{6}=V\)
Now find the value of V

yes..

Answer 19

v= 2?

Answer 20

yes...

Answer 21

Since we need 4.8 L. We will have to add (4.8-2=2.8 L) of water into it

Answer 22

y did u subtract 2 from 4.8?

Answer 23

Because we already have 2 L of 6 M solution. To make it 4.8 L of 2.5 M solution we will have to add 2.8 L of water.

Answer 24

Now after adding water we will get 2+2.8=4.8 L

Answer 25

ooohh okkk

Answer 26

Still confused ?

Answer 27

no i got it couldn't have said it better myself lool
