Hi! I need help on these two questions. Thank u very much!
Transcribed Image Text:Methanol, CH30H (molar mass: 32.042 g/mol), reacts with 02 and can be used as fuel according to the reaction
below (AHxn = -764 kJ/mol CH3OH). What mass of 02 (molar mass: 31.998 g/mol) is consumed when 432 kJ of
heat is given off?
CH3OH +
→ CO2 + 2H20
Select one:
O a. 27.1 g
O b. 83.1 g
Ос. 16.3 g
