Question

0.27 grams of aluminum metal will react with 0.010 l of 6.0 m hydrochloric acid solution according to the following balanced equation. How many moles of hydrogen gas can be formed?

Answer 1

Approximately 0.0125 moles of hydrogen gas can be formed.

Step-by-step explanation:

To determine how many moles of hydrogen gas can be formed, we need to use the balanced equation and the given mass of aluminum. From the balanced equation, we know that 2 moles of aluminum react with 3 moles of hydrochloric acid to produce 3 moles of hydrogen gas. Therefore, we can set up the following proportion:

(0.27 g Al) / (26.98 g/mol) = (x mol H2) / (3 mol HCl)

Solving for x, we find that approximately 0.0125 moles of hydrogen gas can be formed.
