## anonymous one year ago How many liters of 1.5 M HCl solution would react completely with 6.5 moles Ca(OH)2?

1. Rushwr

Did u work this out ?

2. anonymous

I don't know how :/

3. Rushwr

The 1st thing we have to do here is to balance the chemical reaction of these 2

4. Rushwr

The 1st thing we have to do here is to balance the chemical reaction of these 2$Ca(OH)_{2} + 2HCl \rightarrow CaCl _{_{2}} + 2H _{2}O$

5. Rushwr

So according to the equation we can see 1 mole of Ca(OH)2 reacts with 2 moles of HCl right?

6. anonymous

Yes

7. Rushwr

That means 6.5 moles of Ca(OH)2 will react with 13 moles of HCl right

8. anonymous

Yeah

9. Rushwr

so now we know the no of moles and the concentration of HCl Now use n=C x V

10. Rushwr

so V= n divided by C

11. anonymous

Ohh ok

12. Rushwr

So what I got was 8.66 L ? Just double check the answer ! I hope you got it ?!

13. anonymous

I did! Thanks :)
