Jacob is given a beaker full of an unknown liquid and asked to calculate the density of the substance. He places the beaker of liquid on a digital scale. The digital scale displays that the mass of the liquid and the beaker combined is 53.3 grams. Then, Jacob pours the liquid into a graduated cylinder to measure the volume of the liquid. He finds that the liquid has a volume of 16.1 mL. Finally, Jacob calculates the density of the liquid by using the following equation 53.3 g ÷ 16.1 mL = 3.3 g/mL He reports the density of the liquid to be 3.3 g/mL, but his teacher tells him that the density of the liquid is 1.1 g/mL. What was the source of Jacob's calculation error? Jacob did not subtract the mass of the beaker from the combined mass before he used it in the density equation. Jacob divided the mass of the liquid by the volume of the liquid instead of multiplying it to find the density of the liquid. Jacob did not convert the volume of the liquid into the correct units before he used it in the density equation. Jacob used a graduated cylinder instead of a triple beam balance to calculate the volume of the liquid.

Ok, well, I don't know anything about biology but I think I can do this one.

OpenStudy (anonymous):

ok but i was asking if this is where im suppose to be for this question

OpenStudy (anonymous):

Good enough!

OpenStudy (anonymous):

So, like, it says right in the first paragraph what he did wrong, I think.

OpenStudy (anonymous):

yes Starr___Dynasty

OpenStudy (anonymous):

If you're not spotting it, we can go through the choices one by one.

OpenStudy (anonymous):

"The digital scale displays that the mass of the liquid and the beaker combined..." That seems to reveal the problem

OpenStudy (anonymous):

Or BangkokGarrett can just give you the answer, that works too

OpenStudy (anonymous):

he divided the mass of the liquid

OpenStudy (anonymous):

He divided 53.3. That 53.3 is the mass of the liquid and the beaker combined.

OpenStudy (anonymous):

ok so to reveal it most likely the answer would be A

OpenStudy (anonymous):

That's what I'd say too! (unless it has something to do with a triple beam balance but I don't believe it does)

OpenStudy (anonymous):

because he combined right

OpenStudy (anonymous):

Right.

OpenStudy (anonymous):

so it would be A

OpenStudy (anonymous):

it seems to me thts also wht @BangkokGarrett is saying also

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

it is correct wow weve all figured it

Thank all of you for the wrong answer !
