Question 25 a chemist determined by measurements that 0.020 moles of mercury participated in a chemical reaction. calculate the
sammy [17]
To solve this question, we first need to know the mass of one mole of mercury. This can be done by checking the periodic table.

From the periodic table, we can see that:
molar mass of mercury = 200.59 grams/mole.

From the measurements, the chemist found that the participated amount of mercury is 0.02 moles.

We can simply determine the mass of 0.02 moles by doing cross multiplication as follows:
mass of 0.02 moles = (0.02 x 200.59) / 1 = 4.0118 grams

Rounding the answer to 2 significant digits, we get:
mass of 0.02 moles = 4.01 grams
