Q
Q: What is the mass of 3 moles of NaCl?
Solution:
Molar mass of NaCl = 23 + 35.5 = 58.5 g/mol. Mass = moles x molar mass = 3 moles x 58.5 g/mol = 174 g.
Steps: 5
Show Steps
Step 1: Find the molar mass of NaCl. Sodium (Na) has a mass of 23 g/mol and Chlorine (Cl) has a mass of 35.5 g/mol.
Step 2: Add the masses of Sodium and Chlorine together: 23 g/mol + 35.5 g/mol = 58.5 g/mol.
Step 3: Use the formula to find the mass: Mass = moles x molar mass.
Step 4: Substitute the values into the formula: Mass = 3 moles x 58.5 g/mol.
Step 5: Calculate the mass: 3 x 58.5 = 174 g.
