=46.6 grams

How many moles of Methane are in 26.4 Liters of Methane (CH4) at STP?

STP was defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 1 atm (1.01325 × 10⁵ Pa).

The volume in this conditions is 22.4 Liters/mol

How many molecules of methane are in 3.25 moles of methane?

The Avogadro's Number or constant is the number of constituent particles, usually atoms or molecules, that are contained in the amount of substance given by one mole. This value is 6.022×10²³ mol⁻¹

When converting from atoms to moles, you use the Avogadro's Number is 6.022 x 10²³ mol¯¹ to get the correct answer.

11. Consider a Carnot cycle with 2.25 moles of a diatomic ideal gas as the working substance (assume Cv = 2.5*R). The following are the steps of the cycle: Step I: reversible, isothermal expansion at 300.0 °C from 10.00 L to 16.00 L. Step II: reversible, a diabatic expansion until the temperature decreases to 50.0 °C. Step III: reversible, isothermal compression at 50.0 °C. Step IV: reversible, adiabatic compression back to the initial conditions. A. Calculate q, w, ΔU, ΔH,...
