How many grams of carbon dioxide (CO2) are present in 250 L of this gas, measured at C.N.P.T.? Molar mass CO2 = 44 g / mol​

Respuesta :

Answer: 28.95 g/mol

Explanation:

How much of the “stuff” is there? ... CO2: MW = 1x12 + 2x16 = 12 + 32 = 44 grams per mole ... Mass in grams = Molecular weight x Number of moles ... Examples: Hydrogen = H = 1; Carbon = C = 12; Oxygen = O = 16 ... Actually, the value is 28.95 g/mol because of CO2 and rare gases (heavier). ... Today's carbon dioxide.
