A chemist determined by measurements that 0.085 moles of mercury participated lis a chemical reaction. Calculate the mass of mercury that participated in the chemical reaction.
Round your answer to 2 significant digits.
To calculate the mass of mercury that participated in the chemical reaction, we need to know the molar mass of mercury. The molar mass of mercury (Hg) is approximately 200.59 g/mol.
Now, we can use the formula:
Mass = moles x molar mass
Mass = 0.085 moles x 200.59 g/mol
Mass = 17.05 g
Therefore, the mass of mercury that participated in the chemical reaction is approximately 17.05 grams. Rounded to 2 significant digits, the mass is 17 g.
