If it requires 48.3 milliliters of 0.55 molar nitric acid to neutralize 15.0 milliliters of barium hydroxide, solve for the molarity of the barium hydroxide solution. Show all of the work used to solve this problem.
Unbalanced equation: Ba(OH)2 + HNO3 yields Ba(NO3)2 + H2O

Best ResponseYou've already chosen the best response.2First step: You can find the moles of nitric acid using n=cv where n is the number of moles c is the concentration (aka molarity) so 0.55M v is volume and would need to be in litres not millilitres

Best ResponseYou've already chosen the best response.2Second step: Balance chemical equation using the stoichiometric coefficients relate the HNO3 to the Ba(NO3)2 Using the ratio you can convert the moles of HNO3 to moles of Ba(NO3)2

Best ResponseYou've already chosen the best response.2Third Step: After using the ratio you will have the moles of Ba(NO3)2 So you can use the formula c=n/v c is the concentration that you are trying to find n is the moles you found in the previous step v is the volume in litres so the 15mL but converted

Best ResponseYou've already chosen the best response.0ok so the balanced equation is Ba(OH)2 + 2 HNO3 = Ba(NO3)2 + 2 H2O

Best ResponseYou've already chosen the best response.2Yes it would be

Best ResponseYou've already chosen the best response.2So the ratio is 2 to 1 For every 2 moles of HNO3 there is 1 mole of Ba(NO3)2 produced

Best ResponseYou've already chosen the best response.0ok then what do i do

taramgrant0543664

Best ResponseYou've already chosen the best response.2SO since the ratio is 2:1 the moles you found in step 1 you divide that by 2 to get the moles of Ba(NO3)2 and then you can carry on to step 3

Best ResponseYou've already chosen the best response.2mL is volume but since molarity is mol/L we have to convert the millilitres into litres 1L=1000mL

Best ResponseYou've already chosen the best response.0but it's not 1000 ml

Best ResponseYou've already chosen the best response.2That's the conversion 1mL=0.001L 48.3mL=? L

Best ResponseYou've already chosen the best response.2Yes using this and the 0.55M you can find n using the n=cv formula

Best ResponseYou've already chosen the best response.0huh so 0.026565 isn't the answer?

taramgrant0543664

Best ResponseYou've already chosen the best response.2Yes so now we look at the ratio it was 2:1 so to get the moles of Ba(NO3)2 you divide the moles you just got by 2 to get the moles of Ba(NO3)2

taramgrant0543664

Best ResponseYou've already chosen the best response.2Yes so that would be the moles of Ba(NO3)2 So now you put that into the formula c=n/v and as @Photon336 had said you have to use the total volume so you have to add both together and convert that from millilitres to litres

Best ResponseYou've already chosen the best response.2Yeo together that will be the final volume of the solution

Best ResponseYou've already chosen the best response.1@lovingod786 they asked for concentration i think you need the number of moles too so it has to be moles/liter

taramgrant0543664

Best ResponseYou've already chosen the best response.2Nope you have to put it into the formula first c=n/v

Best ResponseYou've already chosen the best response.0ok so c=0.26565/0.0633?

Best ResponseYou've already chosen the best response.20.0132825/0.0633=c

Best ResponseYou've already chosen the best response.1m\[M _{1}V_{1} = m _{2}V_{2} \] \[m_{2} = \frac{ M_{1}V{1} }{V_{2} }\] \[m_{2}] = moles of Ba(OH)2 \[V_{2}] = final volume.

Best ResponseYou've already chosen the best response.2Haha thanks! I try my best! I'm pretty bad at explaining things but this site has made me a lot better at explaining what I mean and @Photon336 is really good at explaining things too, probably one of the better people at explaining things in this section
