What is the mass in grams of Al that were reacted with excess HCl if 2.12 L of hydrogen gas were collected at STP in the followi
Inessa [10]

4.176 g of Al that was reacted with excess HCl if 2.12 L of hydrogen gas were collected at STP in the following reaction.

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

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

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

Given data:

Volume of H_2 (g) = 5.20L

At STP

Pressure= 1 atm

Temperature =273K

R = 0.0821 L.atm/mol K

PV=nRT

n= \frac{PV}{RT}

n= \frac{1 atm X 5.20 L}{0.0821L.atm/mol K}

n= 0.2324 mol H_2

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

=0.2324 mol H_2 X \frac{2 mol Al}{3 mol H_2} X\frac{27 g Al}{1 mol Al}

=4.176 g of Al

Hence, 4.176 g of Al that were reacted with excess HCl if 2.12 L of hydrogen gas were collected at STP in the following reaction.

an acid based titration was performed. it took 27.45 mL of the base, KOH, to titrate 3.115 g HBr, the acid. what was the molarit
sveticcg [70]

Answer:

<u>1.4 M</u>

Explanation:

n(HBr)=3.115/81

so, 3.115/81=0.0385mol

according to the reaction, n(HBr)=n(KOH)=0.038 mol

C(KOH)=n/V=0.0385/0.02745

0.0385/0.02745 =1.4 M

in short the answer is 1.4 M (molarity)
