What is "Molar" Volume?

I had recently been studying about Molar Volume in chemistry. What is it? And is it okay to say that:
Density (ρ) = Molar Mass/Molar Volume

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

I thank you, buddy.

No prob, chemistry is the one thing I'm good at LOL :)

Can you make it more clear? Please elaborate.

What should I explain? The variables?

No. I mean the concept. I'm pretty confused about it.

@Vasu Khera Moles is amount of matter. Molar Volume is how much volume that Mole(matter) occupies. So if a ball with mass 1 Mole occupies 1m31m^{3} volume, then the Molar Volume is 1m31 mole\dfrac{1m^{3}}{1 \ mole} or 1m3 per mole1m^{3} \ per \ mole

@Percy Jackson But ain't "Mole" a number? How can something have a mass equal to a Mole?

Vasu Khera - 2 months, 3 weeks ago

Log in to reply

@Vasu Khera A mole of something has 6.022 × 10²³ atoms, so the ball has 6.022 × 10²³ number of atoms we can say. 6.022 × 10²³ is Avogadro's Number :)

@Vasu Khera About the constant?

Páll Márton (no activity) - 2 months, 3 weeks ago

@Páll Márton (no activity) Not the constant. The "concept", the idea, what is it about?

@Vasu Khera n=mM,m=ρV    n=ρVMn=\cfrac{m}{M},m=\rho V\implies n=\cfrac{\rho V}{M}, but ρ=MVmn=VVm\rho=\cfrac{M}{V_m}\therefore n=\cfrac{V}{V_m}

@Páll Márton (no activity) This? (some text)

@Páll Márton (no activity) No problem buddy. Don't bother.

Vm=VnV_m=\cfrac{V}{n}. This is a constant with a given pressure and temperature for any gases. Standard pressure and 0C:22,41dm3mol10^{\circ}C:22,41\text{dm}^3\cdot\text{mol}^{-1}

Yes your statement is true. Molar Volume is the amount of space that the molar mass(amount of matter) occupies. This is what gives us formula for density @Vasu Khera :)
