Determine the amount (in grams) of a product from given amounts of two reactants, one of which is limiting.

Problem

Given the following reaction:
space, M, g, left parenthesis, O, H, right parenthesis, start subscript, 2, end subscript, plus, 2, H, C, l, right arrow, M, g, C, l, start subscript, 2, end subscript, plus, 2, H, start subscript, 2, end subscript, O
How many grams of M, g, C, l, start subscript, 2, end subscript will be produced from 12, point, 0, space, g of M, g, left parenthesis, O, H, right parenthesis, start subscript, 2, end subscript and 42, point, 0, space, g of H, C, l?
  • 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
grams (round to three significant figures)
