C3H8 (g) + 4C12 (g) → C3H4Cl4 (g) + 4HCI (g) Molar masses listed for the above equation:
C3H8 (g) = 44.1 g/mol
Cl2 (g) = 70.9 g/mol
C3H4Cl4 (g) = 181.9 g/mol
HCI (g) = 36.458 g/mol
A 4.00 mol sample of C3H8 (g) and a 6.00 mol sample of Cl2 (g) are placed in a previously
evacuated vessel, where they react according to the equation above. After one of the
reactants has been totally consumed, how many moles of HCI (g) have been produced?

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
