A student weighs out 0. 0422 g of magnesium metal. The magnesium metal is reacted with excess hydrochloric acid to produce hydro
1 answer:
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.
