Answer:

2.16 moles are lost from the container

Explanation:

Step 1: Data given

Moles of acetylene = 3.86 moles

Volume = 39.2 L

The volume reduces to 17.3 L

Temperature and pressure is constant

Step 2: Calculate the new number of moles acetylene

V1/ n1 = V2/ n2

⇒with V1 = the initial volume in the container = 39.2 L

⇒with n1 = the initial number of moles acetylene = 3.86 moles

⇒with V2 = the new volume in the container after the leak = 17.3 L

⇒with n2 : the new number of moles = TO BE DETERMINED

39.2 L / 3.86 moles = 17.3 L / n2

n2 = 1.70 moles

Step 3: Calculate the loss of moles

Loss of moles = 3.86 - 1.70 = 2.16 moles

2.16 moles are lost from the container

\frac{V_{1} }{n_{1} } =\frac{V_{2} }{n_{2} } where V₁ is a volume, <em>n</em>₁ is a number in moles, V₂ is a second volume, and <em>n</em>₂ is its corresponding number in moles.

In our data:

  • <em>n</em>₁ = 3.86 mol C₂H₂
  • V₁ = 39.2 L
  • V₂= 17.3 L
  • <em>n</em>₂ = ?

Let's plug our values in the equation above.

\frac{39.2}{3.86} =\frac{17.3}{n} \\\\10.2=\frac{17.3}{n} \\\\10.2n=17.3\\\\n=1.70

Note: You could rearrange the equation before plugging in values for less algebraic manipulation.

We're not done yet.  Now, you have to subtract this number of moles from the initial value to find the difference, since the question states "how many moles...have been lost".

3.86-1.70=2.16

<h3>Answer:</h3>

2.16 moles would have been lost

What types of evidence do scientists use to determine evolutionary relationships among groups
lions [1.4K]
There are several things that can help scientists evaluate which category something belongs to. The similarity in features is one of them. If two skulls looked alike, they were probably species of the same evolutionary category. For example say humans and monkeys rather than humans and dogs.
Similarly fossils have helped scientists categorise species. Study of the chromosomes (in cases with available chromosomes) can help scientists figure out a lot about the subjects and categorise them.
