At standard pressure, the molecules of a liquid are much closer together than those in a gas (just look at their relative densities). For some reason, water molecules are much more comfortable with this than are methane molecules. These two have similar molecular masses so you probably want to...
Whenever you graph something, you need to first identify the independant and dependant variables. In this case, y is the independant variable and f(y) is the dependant variable so it is really no different than graphing an equation with x and f(x).
Most graphing calculators will only let you...
The first step is to reread the question part of the problem statement: "Find the ticket price and number of tickets sold that will maximize the airline's REVENUE." This part gives you a strong indication as to what your dependant (y) variable should be.
The first mistake your a making is only a computational one. Try going back to your equation mol * g/mol = g and running your numbers again. I agree that there are 1783.04 moles of HCl in the vat and that the molecular weight of Ca(OH)2 is 74 g/mol.
The second mistake will be easier to find...
I agree with your math used to determine the total mass of 1783.04 moles of Ca(OH)2:
moles Ca(OH)2 * g/moles = g of Ca(OH)2
but your calculations shown are off.
But this mass of base will not lead you to the right answer. Go back to the neutralization reaction (this should have been the...
In regards to your first question: what did you determine to be the final volume of the 0.33 M H2SO4 solution?
A good starting point for the second question is this: figure out how many moles of HCl you have in the vat then determine how many moles of Ca(OH)2 will be required to neutralize them.
