Question

An experiment in your science class lists the materials needed for the lab. It is your job, as a lab partner, to measure out 25 mL of distilled water and 2.5 grams of magnesium. What lab measuring tools would you choose to measure each substance and how would you use each tool to get the correct amounts? Be sure to describe the process you would follow step-by-step.

Answer 1

water would use a measuring cup with milliliters
and you would use a scale to find the weight of magnesium

Answer 2

I would personally use my oral cavity, which is common practice in Chemistry.

jk, beaker?

Answer 3

I think beaker is what I was looking for, thanks guys. What about the process?

Answer 4

pour the water until you have the right ammount

Answer 5

Stare intently at it's abdomen to obtain the appropriate amount of said substance.

Answer 6

You would use a gradated cylinder to get 25 mL of water. And you have to get it so that the bottom of the meniscus is at the 25 mL line

Answer 7

Piece of weighing paper, on a weighing machine. Tare it, measure out 2.5 grams and ta-da

Answer 8

"tare" i love it

Answer 9

So is this good; I would use a beaker to measure how much distilled water will be used for the experiment. (25 mL) I would use a scale to find the weight of the magnesium. (2.5 grams) The correct way to do this would be to pour the distilled water in the beaker until it has reached the correct amount. I would then pour the magnesium on the scale, until it has reached the correct weight.

Answer 10

A beaker isn't as accurate as a graduated cylinder

Answer 11

Okay

Answer 12

I edited it.

Answer 13

Other than that, is it okay?

Answer 14

You transfer the contents of the graduated cylinder into a beaker and then you can add the magnesium. But other than that, it's fine.

You might want to mention the weighing boat you use to get the magnesium.

Answer 15

Weighing boat?

You have to put the magnesium somewhere to weight it. So you put that and then you basically tare it which is resetting the balance to 0, and then add how much Mg you need

Answer 17

Oh okay.

That's what it looks like

Answer 19

rip my medal .-.

Answer 20

Haha you were using kitchen tools not stuff you would find in a lab with adequate funding

Answer 21

i was never in a science class with adequate funding
