I assume you mean excess hydrochloric acid. Balanced equation.
2Al + 6HCl = 2AlCl3 + 3H2
2.70 grams Al (1 mole Al/26.98 grams)(3 mole H2/2 mole Al)(2.016 grams/1 mole H2)
= 0.303 grams hydrogen gas produced

What is the volume of hydrogen gas when a sample of 9 grams of aluminum metal is added to an excess of hydrochloric acid?
9g Al x (1 mol Al/27g Al) x (3mol H2 / 2 mol Al) x (22.4L / 1 mol H2) = 11.2L H2
What has more atoms 17.031 grams of ammonia or 72.922 grams of hydrogen chloride?
Molar mass of ammonia is 17.031 whereas molar mass of hydrogen chloride (or hydrochloric acid) is 36.461. Hence if given masses, there is 1 mole ammonia and 2 moles HCl. Hence there is more number of hydrogen chloride.
How many grams of hydrogen is produced when 167.12 g of hydrochloric acid is reacted with copper?
Cu + 2 HCl --> CuCl2 + H2 167.12 g HCl * (1 mol HCl/36.46 g HCl) * (1 mol H2/2 mol HCl) * (2.02 g/1 mol H2) = 4.629 g H2 4.63 grams of hydrogen gas is produced when 167.12 grams of hydrochloric acid reacts with copper.
How many moles of aluminum are produced from 33 grams of aluminum?
33 grams aluminum (1 mole Al/26.98 grams) = 1.2 moles of aluminum ================

How many grams of aluminum chloride can be made from 67.0 grams of aluminium and excess hydrochloric acid?
The answer is: approx. 327 g.
What is atomic no of hydrochloric acid?
hydrochloric acid does not have an atomic number. Only elements have atomic numbers and hydrochloric acid is a compound composed of two non-metal elements: hydrogen and chlorine, as you might have guessed by the name. However: Hydrogen's atomic number is 1 and Chlorine's atomic number is 17
