To calculate the mass of aluminum that participated in the chemical reaction, we can use the molar mass of aluminum. The molar mass of aluminum is approximately 26.98 grams per mole.
By multiplying the number of moles of aluminum (0.0850 moles) by its molar mass (26.98 g/mol), we can find the mass of aluminum.
0.0850 moles * 26.98 g/mol = 2.2993 grams
Therefore, the mass of aluminum that participated in the chemical reaction is approximately 2.2993 grams.
