How many grams of co2 gas would occupy 33.7 l of volume at a temperature of

–22.2oc and a pressure of 990 mm hg?

93.75 g.

Explanation:

where, P is the pressure of the gas in atm (P = 990 mmHg = 1.3 atm).

V is the volume of the gas in L (33.7 L).

n is the no. of moles of the gas in mol.

R is the general gas constant (R = 0.082 L.atm/mol.K),

T is the temperature of the gas in K (T = – 22.2°C + 273 = 250.8 K).

∴ n = PV/RT = (1.3 atm)(33.7 L)/(0.082 L.atm/mol.K)(250.8 K) = 2.13 mol.

The no. of grams of CO₂ = no. of moles x molar mass = (2.13 mol)(44.01 g/mol) = 93.75 g.

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
