ok im here

ok so the balanced equation is Ba(OH)2 + 2 HNO3 = Ba(NO3)2 + 2 H2O

Yes it would be

So the ratio is 2 to 1
For every 2 moles of HNO3 there is 1 mole of Ba(NO3)2 produced

ok then what do i do

C=N/V
0.55M=n/v

i thought ml was volume

mL is volume but since molarity is mol/L we have to convert the millilitres into litres
1L=1000mL

but it's not 1000 ml

That's the conversion
1mL=0.001L
48.3mL=? L

0.0483L

Yes using this and the 0.55M you can find n using the n=cv formula

0.0483*0.55=0.26565

Close I think you're missing a 0 in there

0.026565

remember to add both volumes (V1 + V2) to get your final volume

huh so 0.026565 isn't the answer?

0.026565/2=0.0132825

so 48.3+15.0?

Yeo together that will be the final volume of the solution

48.3+15.0=63.3 ---> 0.0633

yep

so thats the final answer?

Nope you have to put it into the formula first c=n/v

ok so c=0.26565/0.0633?

0.0132825/0.0633=c

0.21

yep that would be correct

so thats the final answer then??

??

OK THX

Well do not did

Yeah @Photon336 is good too when I first got here they use to help me

thanks guys
