9.6: Combining Stoichiometry and the Ideal Gas Laws
WebWith the ideal gas law, we can use the relationship between the amounts of gases (in moles) and their volumes (in liters) to calculate the stoichiometry of reactions involving gases, if the pressure and temperature are known. This is important for several reasons. WebCHM 130 Stoichiometry Worksheet The following flow chart may help you work stoichiometry problems. Remember to pay careful ... B. Calculate the volume of carbon dioxide gas produced at STP if 100.0 grams of glucose reacts. C. If 17.5 moles of ethanol were produced, how many moles of glucose were there in the beginning? WebThis worksheet provides practice in stoichiometry problems involving gases at standard conditions (STP) and non-standard conditions. The relevant formulas for calculations are: n = V m V and n = RT PV where V m = 22.4 dm3 mol–1 at STP (T = 0 C, P = 1 atm).
