How many milliliters of 0.130 M HCl are needed to completely neutralize 41.0 mL of 0.107 M Ba(OH)2 solution?
Anvisha [2.4K]

54 mL Ba(OH)2x(0.101 mol Ba(OH)2/1000 mL) x (2 mol OH-/ 1 mol Ba(OH)2 )  = 0.0109 mol OH-

                                 

0.0109 mol OH-x (1mol HCl/ 1 mol OH- ) = 0.0109 mol HCl

                                                     

0.109 mol HCl/(0.130 mol/L HCl) =  0.0839 L HCl

0.0839 L HCl * 1000mL = 83.9 mL of 0.130 M HCl

b) 1  ounce = 1 / 16 lb = 1/16 x 453.6 g = 28.35 g.

1 troy ounce = 31.103 g

so 1 troy ounce is heavier than 1 ounce.
