Problem

Given the following reaction:
space, Z, n, plus, 2, H, C, l, right arrow, Z, n, C, l, start subscript, 2, end subscript, plus, H, start subscript, 2, end subscript
How many moles of Z, n, C, l, start subscript, 2, end subscript will be produced from 55, point, 0, space, g of Z, n, assuming H, C, l is available in excess?
  • Your answer should be
  • an integer, like 6
  • an exact decimal, like 0, point, 75
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
moles (round to three significant figures)
