Explanation Given data: M ( He ) = 2.0 g . Formula used: Write the expression for number of moles ( n ) . n = M ( in grams ) M mol (1) Here, M mol is the molar mass, and M is the mass. Write the expression for quantity of heat ( Q ) for a constant-volume process. Q = n C V Δ T (2) Here, C V is the molar specific heat at constant volume, and Δ T is the change in temperature. One mole of atoms for each element has a mass in grams which is equal to the atomic mass number. Refer to TABLE 12.1 in the textbook, the molar mass for helium ( M mol ( He ) ) is 4 g mol . Modify equation (1). n He = M ( He ) M mol ( He ) Substitute 2.0 g for M ( He ) and 4 g mol for M mol ( He ) , n He = 2.0 g 4 g mol = 0.5 mol Refer to TABLE 12.6 in the textbook for Molar specific heats of gases at 20 ° C , that is C V ( He ) = 12.5 J mol ⋅ K . Modify equation (2). Q He = n He C V ( He ) Δ T Substitute 0.5 mol for n He and 12.5 J mol ⋅ K for C V ( He ) , Q He = ( 0.5 mol ) ( 12.5 J mol ⋅ K ) Δ T Q He = ( 6.25 J K ) Δ T (3) Refer to TABLE 12.1 in the textbook, the molar mass for oxygen is 16 g mol . The total molar mass of oxygen gas ( M mol ( O 2 ) ) is 32 g mol ( 16 g mol + 16 g mol ) . Modify equation (1). n O 2 = M ( O 2 ) M mol ( O 2 ) Substitute 32 g mol for M mol ( O 2 ) , n O 2 = M ( O 2 ) ( 32 g mol ) Refer to TABLE 12.6 in the textbook for Molar specific heats of gases at 20 ° C , that is C V ( O 2 ) = 20
