A student weighs out 0. 0422 g of magnesium metal. The magnesium metal is reacted with excess hydrochloric acid to produce hydrogen gas. A sample of hydrogen gas is collected over water in a eudiometer at 32. 0°c. The volume of collected gas is 43. 9 ml and the atmospheric pressure is 832 mmhg. Using the experimentally collected data, calculate r and the percent error.

Sagot :

The value of r is 0.0868 and the error percentage is 5.78%.

  • The student weights 0.0422 grams of magnesium; thus, we may deduce that the magnesium he used is the mass of the magnesium over the additional mass, which is 0.024422.
  • That is roughly equal to 0.001758.
  • It also asserts that too much hydrochloric acid can react with magnesium, releasing hydrogen gas as a result.
  • A sample of hydrogen gas is collected over water in a meter at a volume of 43.9 cc and a maximum pressure of 22 cc.
