0.0840 dm3 of a gas is collected by water displacement at 22.00 C and 85.0 kPa. What volume would the dry gas occupy at standard pressure and 22.00 C? (water vapor pressure at 22.00 C = 2.6 kPa) I'm stuck on solving this one, plz show work! Will also mark you Brainliest!

Calculate the molar mass of aluminum oxide (al2o3). express your answer to four significant figures.

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!

Which symbol can be used to indicate the pressure at which a chemical reaction is carried out? 25°c 2 atm pa
