<h2>Answer: i agree B</h2><h2>Explanation:</h2>

A the gun wasn't found. this would be an issue but still possible to determine distance with gunpoweder residue

C a hollow point round was used. that is just some type of bullet. i dont remember any specific lesson on bullet identification

D the gun was decades old. this could also be an issue, but it doenst have anything to do with distance

So it must be B. unless the victim could tell you how far the shooter was. but then we would have to consider consciousness, if the victim was facing the shooter, and if the victim was sober. but that's juts overthinking things. it 's most likely B

I would think 2. The victim survived the incident because the victim would have moved or gotten up, which changes the distance between the victim and the gun.

How many moles does 13.3 g of Cu contain?
mariarad [96]
<h2>Hello!</h2>

The answer is:

There are 0.209 moles of Cu in 13.g of Cu

Why?

To calculate how many moles does a sample of any element has, we need to use its atomic mass

We are working with Copper (Cu), so we need to find its atomic mass to calculate how many moles does 13.3 g of Cu contains.

So, calculating we have:

Cu=63.54\frac{g}{mol}

We have that there is 1 mol per 63.54 grams of Cu.

Now, converting we have:

13.3g*\frac{1mol}{63.54g}=0.209moles

We have that there are 0.209 moles of Cu in 13.g of Cu

Have a nice day!
