C12, point, 01
O16, point, 00
Using the information in the table, calculate the number of moles in a 2, point, 03, space, k, g sample of citric acid (CX6HX8OX7\ce{C6H8O7}).
Write your answer using three significant figures.
  • Your answer should be
  • an integer, like 6
  • 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
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, start text, p, i, end text or 2, slash, 3, space, start text, p, i, end text
