An 80L capacity steel cylinder contains H2 at a pressure of 110 atm and 30 ° C, after extracting a certain amount of gas, the pr
icang [17]

Answer:

2200 L

Explanation:

Ideal gas law:

PV = nRT,

where P is absolute pressure,

V is volume,

n is number of moles,

R is universal gas constant,

and T is absolute temperature.

The initial number of moles is:

(110 atm) (80 L) = n (0.0821 L atm / K / mol) (30 + 273.15) K

n = 353.58 mol

After some gas is removed, the number of moles remaining is:

(80 atm) (80 L) = n (0.0821 L atm / K / mol) (30 + 273.15) K

n = 257.15 mol

The amount of gas removed is therefore:

n = 353.58 mol − 257.15 mol

n = 92.43 mol

At normal conditions, the volume of this gas is:

PV = nRT

(1 atm) V = (92.43 mol) (0.0821 L atm / K / mol) (273.15 K)

V = 2162.5 L

Rounded, the volume is approximately 2200 liters.

Using the determined equivalence point from question 2 and the balanced reaction of acetic acid and sodium hydroxide, calculate
goldenfox [79]

Answer:

Molarity of the packet is 0.5M

Explanation:

In the reaction of acetic acid with NaOH:

CH₃COOH + NaOH → CH₃COO⁻ + H₂O + Na⁺

<em>1 mole of acetic acid reacts with 1 mole of NaOH.</em>

<em />

When you are titrating the acid with NaOH, you reach equivalence point when moles of acid = moles of NaOH.

Moles of NaOH are:

3.0mL = 3.0x10⁻³L ₓ (0.1 mol / L) =<em> 3.0x10⁻⁴ moles</em> of NaOH = moles of CH₃COOH.

Now, you find the moles of acetic acid in the hot sauce packet. But molarity is the ratio between moles of the acid and liters of solution.

As you don't know the volume of your packet, <em>you can assume its density as 1g/mL. </em>Thus, volume of 0.6g of hot sauce is 0.6mL = 6x10⁻⁴L.

And molarity of the packet is:

3.0x10⁻⁴ moles acetic acid / 6x10⁻⁴L =

<h3>0.5M</h3>
