calcium hydroxide reacts in a neutralization reaction with sulfuric acid in a 1:1 ratio to form water and calcium sulfate. if you have 23.5 grams of calcium hydroxide, how many milliliters of water can you form?

how do i use dimensional analysis to solve this?

    Ca(OH)2 + H2SO4 -> 2 H2O + CaSO4

    The molar mass of Ca(OH)2 is 40 + 2*17 = 74 g/mole. So you consume 3.15 moles of Ca(OH)2 and form twice as many moles of H2O. Use the ideal gas law to convert that to VAPOR volume.

    I don't see how dimensional analysis helps with this, except to keep track of dimensions.

    You need to use dimensional analysis only when the two materials react in other than a 1:1 ratio.
