A mixture of methane and carbon dioxide gases contains methane at a partial pressure of 431 mm Hg and carbon dioxide at a
KatRina [158]

Answer:

XCH₄ = 0.461

XCO₂ = 0.539

Explanation:

Step 1: Given data

  • Partial pressure of methane (pCH₄): 431 mmHg
  • Partial pressure of carbon dioxide (pCO₂): 504 mmHg

Step 2: Calculate the total pressure in the container

We will sum both partial pressures.

P = pCH₄ + pCO₂

P = 431 mmHg + 504 mmHg = 935 mmHg

Step 3: Calculate the mole fraction of each gas

We will use the following expression.

Xi = pi / P

XCH₄ = pCH₄/P = 431 mmHg/935 mmHg = 0.461

XCO₂ = pCO₂/P = 504 mmHg/935 mmHg = 0.539

typical seawarer contains 2.7g of salt (sodium chloride,Nacl)per 100ml (100*10-3L).what is the molarity of Nacl in the ocean?​
faust18 [17]

Answer:

Molarity = 0.5 M

Explanation:

Given data:

Mass of NaCl = 2.7 g

Volume = 100 mL(100×10⁻³L)

Molarity of solution = ?

Solution:

Formula:

Molarity = number of moles / volume in litter

Number of moles:

Number of moles = mass/ molar mass

Number of moles = 2.7 g/ 58.5 g/mol

Number of moles = 0.05 mol

Molarity = number of moles / volume in litte

Molarity = 0.05 mol / 100×10⁻³L

Molarity = 0.5 M

How many moles are contained in a 4.67-l sample of gas at 30 c and 199 kpa?
valentina_108 [34]

Using ideal gas equation,

PV=nRT

P=199 kpa

V=4.67 L

T=30+273K= 303K

n= number of moles of gas

R=8.321 L·kPa·K-1·mol-1

So using ideal gas equation,

n=PV/RT

=199*4.67/8.321*303\

=0.37 mol
