<span>Step 1: Convert the given amount to moles, by dividing the given amount by the molecular weight of the compound.
5 g C3H8 (1 mol / 44 g C3H8) = 0.114 mol C3H8
Step 2: Find the mole ratio between the given and the desired target (in this case water). The mole ratio between C3H8 and water is 1:4, that is, you can make 4 times as much water from a one C3H8 (assuming that it isn't the limiting reactant).
Line 1: straight horizontal line Line 2: straight line at a slope Line 3: exponential growth curve Line 4: the topmost curve (the one that initially increases but then starts levels out)
