what is the molarity of a HCl solution if a 10.0 mL sample is neutralized by a 44.3 mL of a 0.111 molar solution of Ba(OH)2

Ba(OH)2(aq) + 2HCl(aq) -----------------> BaCl2(aq) + 2H2O(l)

1mole 2 moles

HCl Ba(OH)2

M1 = M2 = 0.111M

V1 = 10ml V2 = 44.3ml

n1 = 2 n2 = 1

M1V1/n1 = M2V2/n2

M1 = M2V2n1/V1n2

= 0.111*44.3*2/10*1

= 0.983M

The molarity of HCl is 0.983M

Calculate the molarity of an HCl solution if a volume of 39.54 mL of this solution is required to titrate 0.2348 g Na2CO3. (Bromocresol green is used as an indicator). This HCl solution (calculated in question 1.) is then used to analyze an unknown sample. Calculate the % Na2CO3 in the sample if a volume of 23.44 mL of the HCl solution is required to titrate 0.4089 g of the sample
