MASS-VOLUME AND VOLUME-VOLUME PROBLEMS
Follow all RULES. Remember to always start with a balanced equation.
A. Balanced Equation:
_________________________________
How many liters of O2 at STP are required to burn 3.86 L of carbon monoxide
to produce carbon dioxide?
*****************************************************************
B. Given:
HgO (s)

Hg (l) + O2 (g)
How many liters of oxygen gas at STP are released if 2.50 g HgO decompose?
*******************************************************************
C. Given: Mg(s) + H2SO4 (aq)  MgSO4 + H2(g)
Calculate the mass of Mg metal that reacts with H2SO4 to produce 0.225 liters
of H2 at STP.
*******************************************************************
D. Balanced Eq: ___________________________________________
Calculate the volumes of:
a) chlorine gas and
b) oxygen gas
that react to yield 1.75 L of dichlorine trioxide. (Assume all gases are at STP)
