How many grams of water will be needed to produce 1.5 moles of acetylene gas?

Answer 1

See discussion.

Acetylene gas can be obtained by the reaction of water with calcium carbide, but it cannot be obtained directly from water:

#{C-=C}^(2-)Ca^(2+) + H_2O(l) rarr H-C-=C-H(g)uarr + Ca(OH)_2(aq)#
Such a reaction was the basis of an early miners' lamp. If you need #1.5*mol# acetylene you need #1.5*mol# water, i.e. a mass of #27# #g#.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
