Mass of Aluminum= 8.829 g
<h3>Further explanation</h3>
Given
Reaction
2Al + 6HCl → 2AlCl₃ + 3H₂
Required
mass of Aluminum
Solution
At STP, 1 mol gas = 22.4 L
For 11 L of Hydrogen :
= 11 : 22.4
= 0.491
From equation, mol ratio Al : H₂ = 2 : 3, so mol Al :
= 2/3 x mol H₂
= 2/3 x 0.491
= 0.327
Mass Aluminum(Ar=27 g/mol) :
= 0.327 mol x 27 g/mol
= 8.829 g
the metric system is that volume is derived from the basic length measurement
mL and cm^3
What is metric system?
A system of measurements is called the metric system. It is employed in calculations and research across the globe. Here are some instances of measurements made with the metric system:
- The unit used to measure lengths and distances is the meter. In daily life, we use this unit to measure things like the length of a piece of clothing, the distance from school to home, etc.
- You may have noticed that the bag of your favorite food has a weight listed on it. 250 grams of potato chips, as an illustration. The unit of weight used here is the gram.
- Similar to this, the bottle of your preferred beverage has a volume indication (for example, 250 milliliters of cola). The unit of volume used here is the milliliter.
