Question

What is the weight (in grams) of a liquid that exactly fills a 465.0 milliliter container if the density of the liquid is 0.982 grams over milliliter? Round to the nearest hundredth when necessary and only enter numerical values, which can include a decimal point

Answer 1

If you know the density of the liquid, and you know how much volume it takes up, then finding the weight of that amount of liquid would simply be:
weight = density * volume
By the way, is this taken off of an online test or something? Not to make an accusation, but the wording of the problem makes me a little bit suspect

Answer 2

im not sure

Answer 3

Container: \(465.0\) \(mL\)
Liquid density: \(0.982\) \(g/mL\)

So we have 465.0 milliliters of a liquid with density 0.9872 grams per milliliter. We can resolve this for weight by multiplication or dimensional analysis:\[465.0mL\cdot\frac{0.982g}{mL}\]You can cross-cancel the milliliters out because one is in the numerator and one is in the denominator. This concept is similar to simplifying fractions.

Answer 4

if im honest I suck at math

Answer 5

So after doing that, we'd have this:\[465.0\cdot0.982g\]This only has one unit now, grams. So if you multiply you should get the final result.

Answer 6

Nevermind, it's probably just for an online homework assignment. I don't know how classes do it these days.
I should have mentioned the units like kittybasil too; in other questions you might have to convert between units, but they happened to work out nicely for this one

Answer 7

thank you both

Answer 8

Ooh, I hate those. Those are so irritating.
But yeah, this one worked out quite well!

Answer 9

No problem 😊

Answer 10

:)

Answer 11

I got 2.71

Answer 12

is that right?

Answer 13

Er... how did you get that?

Answer 14

ion even know

Answer 15

It's okay, we can try again. Just checking though - you do get everything I explained before right?
