A chemist determines by measurements that 0.0550 moles of chlorine gas participate in a chemical reaction calculate the mass of chlorine gas that participates
Be sure your answer has correct number of significant digits in g
To calculate the mass of chlorine gas, we need to multiply the number of moles (0.0550 moles) by the molar mass of chlorine gas.
The molar mass of chlorine (Cl₂) is 70.906 g/mol.
Mass = Number of moles × Molar mass
Mass = 0.0550 moles × 70.906 g/mol
Calculating the result:
Mass = 3.9493 g
Answer: The mass of chlorine gas that participates in the chemical reaction is 3.9493 g.
To calculate the mass of chlorine gas that participates in the reaction, we need to use the molar mass of chlorine.
The molar mass of chlorine (Cl2) is 35.45 g/mol.
Now, we can use the given number of moles of chlorine gas (0.0550 moles) and the molar mass to calculate the mass.
Mass = number of moles × molar mass
Mass = 0.0550 moles × 35.45 g/mol
Calculating the mass:
Mass = 1.9275 g
Since the number of significant digits in the given value (0.0550 moles) is 4, we need to round our final answer to 4 significant digits.
Therefore, the mass of chlorine gas that participates in the reaction is 1.928 g.
To calculate the mass of chlorine gas that participates in the chemical reaction, you need to use the molar mass of chlorine gas and the number of moles.
The molar mass of chlorine gas (Cl2) is 70.906 g/mol.
Step 1: Use the given number of moles (0.0550 moles) and multiply it by the molar mass of chlorine gas to find the mass in grams.
0.0550 moles x 70.906 g/mol = 3.9493 grams
Step 2: Round the answer to the correct number of significant digits. In this case, we have four significant digits in the given number of moles, so our answer should have four significant digits as well.
Therefore, the mass of chlorine gas that participates in the chemical reaction is 3.949 grams.
