`you have to be careful about pouring drano down your pipes since it is mainly hydrochloric acid--you can't do it if they are made of aluminum because it will dissolve them! you can't acid clean your aluminum auto parts for the same reasons: 2 al + 6 hcl → 2 alcl3 + 3h2. if you were able to dissolve 10.0 mol of al, how many many moles of hydrogen gas could you make? note: all numbers located immediately after elemental symbols should be considered subscripts.
a. 3.00 moles
b. 6.00 moles
c. 1.50 moles
d. 15.0 moles

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
