Final answer:
The mass of 0.63 moles of sulfur is 20.16 grams, calculated by multiplying the number of moles by the molar mass of sulfur, which is 32 g/mol.
Step-by-step explanation:
The mass of 0.63 moles of sulfur can be calculated using the molar mass of sulfur, which is 32 g/mol. By multiplying the molar mass with the number of moles, we obtain the mass in grams:
Mass = moles × molar mass
Mass = 0.63 moles × 32 g/mol
Mass = 20.16 grams of sulfur
This calculation shows that 0.63 moles of sulfur translates to 20.16 grams. The molar mass of sulfur is a constant value that applies universally, allowing chemists to convert between moles and mass easily.
