A chemist determines by measurements that 0.0150 moles of chlorine gas participate in a chemical reaction. Calculate the mass of chlorine gas that participates. round your answer to significant digits.
Accepted Answer
Here's how to calculate the mass of chlorine gas:
1. Find the molar mass of chlorine gas (Cl₂): Chlorine's atomic mass is 35.45 g/mol. Since chlorine gas is diatomic (Cl₂), its molar mass is 2
35.45 g/mol = 70.90 g/mol.
2. Use the formula: mass = moles
molar mass
3. Plug in the values: mass = 0.0150 mol
70.90 g/mol = 1.06 g
Therefore, the mass of chlorine gas that participates in the reaction is 1.06 g.
