Question

A researcher is using 4.21 x 10²³ molecules of chlorine gas (Cl₂) in an experiment. How many grams of chlorine is the researcher using? Remember to include units (abbreviated appropriately) and the substance in your answer. Round your answer to the nearest 0.01.

(Thank you so much)!! in advance. !

Answer 1

this problem is a unit conversion question that can be solved using dimensional analysis as follows:

4.21E23 molecules X (1 mole/6.022E23molecules) X (70.906 g/mole Cl2)= 49.57 g
