A25.00 ml flask contains methane (ch4) gas at 22.5°c. the pressure in the flask is 225.2 mmhg. how many moles of methane are in the flask?

= 0.232 moles

Using the ideal gas Law ;

n = PV/RT ; Where, R is the ideal gas constant (0.0821 L atm / K mole), n is the number of moles, P is the pressure, V is the volume and T is the temperature.

V = 0.025 L, T = 22.5 +273 = 295.5 K, P = 225.2 mmHg

n = (225.2 × 0.025)/(295.5 × 0.0821 )

  = 0.232 moles

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
