Hope you understand how to work out those types of questions now xD ;)
They are both true glad i could help
I believe it was Hiroshima. Followed by Nagasaki. Moscow was never bombed in my knowledge, and Auschwitz was a death camp, so it wasn't bombed.
NaOH + HBr =⇒ NaBr + H2O
35.0 ml HBr x 1 liter/1000 mL x 0.140 moles HBr/ liter = 0.0049 moles HBr
0.0049 moles HBr x 1mole NaOH/1mole HBr = 0.0049 moles HBr
0.0049 moles HBr x 1 liter NaOH/0.200 moles NaOH x 1000 mL/1liter= 24.5 mL NaOH
