Please help!<br><br> Calculate the percent by mass of water in FeCl2 · 4H20.
Sedaia [141]

Answer:

36.23 %

Explanation:

Let's <em>assume we have 1 mol of FeCl₂ · 4H₂O</em>. In that case we would have:

  • 1 mol of FeCl₂, weighing 126.75 g (that's the molar mass of FeCl₂), and
  • 4 moles of H₂O, weighing (4 * 18 g/mol) 72 g.

Now we can <u>calculate the percent by mass of water</u>:

  • % mass = mass of water / total mass * 100%
  • % mass = \frac{72}{72+126.75} * 100% = 36.23 %
