anonymous · Answer

I balanced the equation already, Ba(OH)2 + 2 HNO3 = Ba(NO3)2 + 2H2O, can somebody please help me from here?

Hold on.

@primeralph would you mind typing the numbers out and explaining them so i can comprehend a little bit better please?

primeralph · Answer

M = n/V, 
M =  molarity, n= number of moles, V = volume
n Ratio is  1:2
So, (M_1*V_1)/(M_2*V_2) = 1/2
(18.2*0.45)/(x*38.5) = 1/2

abb0t · Answer

molarity is moles/ volume. So find the moles and then divide by volume.
