Find the volume of 2.40 moles of gas whose temperature is 50.0°C and whose pressure is 2.00 atm.
DanielleElmas [232]
PV=nRT
n=2.4 moles
T=273.15+50=323.15K
P=2*101325=202650 Pa
R=8.31


Solve for V:
V=nRT/P=2.4*8.31*323.15/202650=.032m^3

If 0.0106 g of a gas dissolves in 0.792 L of water at 0.321 atm, what quantity of this gas (in grams) will dissolve at 5.73 atm?
Alex73 [517]

Answer:

0.189 g.

Explanation:

  • This problem is an application on <em>Henry's law.</em>
  • Henry's law states that the solubility of a gas in a liquid is directly proportional to its partial pressure of the gas above the liquid.
  • Solubility of the gas ∝ partial pressure
  • If we have different solubility at different pressures, we can express Henry's law as:

<em>S₁/P₁ = S₂/P₂,</em>

S₁ = 0.0106/0.792 = 0.0134 g/L and P₁ = 0.321 atm

S₂ = ??? g/L and P₂ = 5.73 atm

  • So, The solubility of the gas at 5.73 atm (S₂) = S₁.P₂/P₁ = (0.0134 g/L x 5.73 atm) / (0.321 atm) = 0.239 g/L.

<em>The quantity in (g) = S₂ x V = (0.239 g/L)(0.792 L) = 0.189 g.</em>

What is the empirical formula of a compound that is made of 3.80g of phosphorus and 0.371g of hydrogen?
lys-0071 [83]

You start by diving each quantity given by the atomic wight of each element:

Phosphorus (P)   \frac{3.8}{31} =0.123

Hydrogen (H)   \frac{0.371}{1} =0.371

Then you divide by the lowest number:

\frac{0.123}{0.123} = 1 for phosphorus

\frac{0.371}{0.123} = 3 for hydrogen

So the empirical formula will be:    

PH_{3}

Methanol and butanol are alcohols. Alcohols have the same_______________ as alkanes and the __________ identifies the compound a
Margarita [4]

Answer:

Methanol and butanol are alcohols. Alcohols have the same_______________ as alkanes and the __________ identifies the compound as an alcohol.

Explanation:

Alcohols belong to a group of organic compounds which contain -OH group as the functional group.

So alcohols have the same carbon -hydrogen bonds as alkanes and the        -OH functional group identifies the compound as an alcohol.
