From the mass of Al reacted, how many moles are present? What is the mole ratio between Al and H2 in the balanced chemical react
tigry1 [53]

Answer:

From the mass of Al reacted, how many moles are present? We don't have the mass of Al reacted

What is the mole ratio between Al and H2 in the balanced chemical reaction?

By stoichiometry, ratio between Al and H₂ is 3:2

What units are required on the temperature when doing calculations with gases? °K degrees

The value of R is 0.082 L.atm/mol.K

Explanation:

A chemical reaction for this can be this one:

2Al (s)  + 6HCl (aq)  →  2AlCl₃(aq)  + 3H₂ (g)

Balanced

To get the moles which are present in the mass of Al reacted you must calculate:

Al Mass / Al molar mass = Al moles

The Ideal Gas equation is this one:

Pressure . Volume = n° moles . R (gases constant) . T°K

The temperature must be in K, because the units of R

We usually use R = 0.082 L.atm/mol.K
