Chapter 16 Basic Home njit2.mrooms.net P Flag question 22.6 mL of 0.420 M HBr is mixed with 72.2 mL of 1.31 M HCI. What is the molarity of the H? Strong acid+ strong acid Answer: Not yet answered Marked out of 1.00 Flag question 33.9 mL of 0.290 M NaOH is mixed with 68.9 mL of 0.51 M LioH. What is the molarity of the OH? Strong base strong base Answer

Solution

moles HBr = 0.0226 L x 0.420 M=0.009492
moles HCl = 0.0722 L x 1.31 M=0.0945
total moles H+ = 0.1039
total volume = 0.0948
[H+]= 0.1039/ 0.0948= 1.0959M

question 2 can be similarly solved for OH-

moles NaOH = 0.0339 L x 0.290 M=0.009831
moles LiOH = 0.0689L x 0.51 M=0.03514
total volume = 0.1028L
[OH-]= 0.03514/0.1028=0.3418M
