Step 1: Identify the mass of sodium (Na) you have, which is 50 grams.
Step 2: Find the molar mass of sodium (Na). It is 23 grams per mole (g/mol).
Step 3: Use the formula to calculate the number of moles: Number of moles = mass / molar mass.
Step 4: Plug in the values: Number of moles = 50 grams / 23 g/mol.
Step 5: Calculate the result: 50 / 23 is approximately 2.17.
Step 6: Conclude that there are approximately 2.17 moles of sodium in 50 grams.
Molar Mass – The mass of one mole of a substance, expressed in grams per mole (g/mol), which is used to convert between grams and moles.
Mole Calculation – The process of determining the number of moles from a given mass using the formula: number of moles = mass (g) / molar mass (g/mol).
