A chemist collects a sample of hydrogen. She collects 125 mL at 1 atm. What would be the volume of the gas when the pressure is 768 mm Hg?

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:

Consider the reaction of a(g) + b(g) + c(g) => d(g) for which the following data were obtained: experiment initial [a], mol/l initial [b], mol/l initial [c], mol/l initial rate, mol/l.s 1 0.0500 0.0500 0.0100 6.25 x 10^-3 2 0.100 0.0500 0.0100 2.50 x 10^-2 3 0.100 0.100 0.0100 1.00 x 10^-1 4 0.0500 0.0500 0.0200 6.25 x 10^-3 what is the rate law for the reaction?

Can someone me with 6 to 10 plz this is for masteries test.
