weekly math question

[Lexi Persimmons]

what would be the volume of a gas tank that has a density of 10 kg/liter and a mass of 3
kilograms?



density = mass/volume

a. 30
b. .3
c. 3
d. 15
e. no answer

true it's pretty foul

[blumpkin blownuts]

not enough info given

if you know the molecular weight of the gas, temperature and pressure then you can use PV=nRT

ρ = m/V is for density of a liquid or non-hollow solid - applying that only gives you the volume of material used in the tank's construction. to get the volume of the tank using this formula you'd also need to know the shape and thickness of the tank

[juji]

it's a gas. PV=nRT
since there are initial values missing, assume STP

Are you sure?

[blumpkin blownuts]

Are you sure?

still not enough info given, even assuming STP you still would need to know what gas is in it
the answer is E

You can just find the missing variable

Volume = Mass/Desnity as 3/10

3/10 = 0.3

[blumpkin blownuts]

Volume = Mass/Desnity as 3/10

3/10 = 0.3

thats the volume of the material the tank is made of. the tank is hollow so the volume of the tank depends on the volume of the material and the tank's physical dimensions

Are you saying gas tank is material?

[blumpkin blownuts]

Are you saying gas tank is material?

right, a lump of material which has been hollowed-out in order to contain a gas

[blumpkin blownuts]

look at it like this - lisa is a gas tank:
☑ clump of material
☑ hollow on the inside
☑ full of hot air
☑ pressurized

juji is correct

[blumpkin blownuts]

juji is correct

you're retarded

if I take X kilograms of steel, it has volume Y
if I machine that volume of steel into the shape of a hollow tank, then that tank has volume >Y

no you are making an ass of yourself as usual

juji is correct

you keep making this much of an ass out of yourself ramen will come stick her tongue in you

Pretty sure you're trolling me... but THIS is as simple as it gets:
I take a party balloon containing 2g of rubber.
I blow the balloon up part way - the mass and volume of the rubber doesn't change.
Then I blow up the balloon even bigger - the mass and volume of rubber still doesn't change.

The rubber itself doesn't change in volume - the only volume that has changed is the volume of air inside the rubber tank.

If you don't see it by now you'll never see it. But I'll be glad to make a bet with you and ask an expert

juji is correct

[blumpkin blownuts]

so the density of clump is equal to her mass, divided by (the volume of liquid she displaces minus the amount of hot air contained)
basically she has negligible density
