Acetone is a common solvent and has a density of 0.7899 g/mL. What volume of acetone, in mL, has a mass of 28.7 g?
Svet_ta [14]
Density = 0.7899 g/mL

mass = 28.7 g

Volume = ?

therefore:

D = m / V

0.7899 =  28.7 / V

V = 28.7 / 0.7899

V  = 36.333 mL

You place air in a sealed can at standard temperature and pressure (STP). You double its absolute temperature (K) while leaving
AnnZ [28]

Answer:

Pressure will double

Explanation:

Gay - Lussac Law => P ∝ T with volume and mass held constant.

=> P₁/T₁ = P₂/T₂ => P₂ = P₁T₂/T₁

T₂ = 2T₁

P₂ = P₁(2T₁)/T₁ = 2P₁

Double absolute temperature => double pressure

Which of the following gases effuses the fastest at a given temperature?
Sholpan [36]

Answer: -

H₂ will diffuse the fastest.

Explanation: -

According to Graham's Law of Diffusion

The rate of diffusion is inversely proportional to the square root of it's density or molar mass. So the lower the molar mass faster the rate of diffusion.

Molar mass of Ne = 20 g / mol

Molar mass of CH₄ = 12 x 1 + 1 x 4 = 16 g /mol

Molar mass of Ar = 40g / mol

Molar mass of H₂ = 1 x 2 = 2 g / mol

Thus H₂ will diffuse the fastest.

The volume of a gas is 0.30 L when the pressure is 4.00 atm. At the same temperature,
padilas [110]

Answer:

The presion is 0.6 atm

Explanation:

P1V1=P2V2

P2 = P1V1/V2

P2 = (4.00 atm * 0.30 L) / 2.0 L

P2= 0.6 atm
