mols NaAc = grams/molar mass
M = mols/0.750L = ? = about 0.06
What is the molarity of a solution made by dissolving 4.14 g of sodium acetate in water and diluting to 750. mL? (molar mass NaC2H3O2 is 82.0 g/mol.)
.67137, but that wasn't right.
An open-ended mercury manometer is used to measure the pressure exerted by a trapped gas as shown in the figure. Atmospheric pressure is 750. mmHg. What is the pressure (in mmHg or torr) of the trapped gas if h =23 cm?
I got 893.462, but that was also wrong. Any help please?
