Q
Q: How many moles are in 50 grams of sodium (Na)?
Solution:
Molar mass of Na = 23 g/mol. Number of moles = mass / molar mass = 50 g / 23 g/mol ≈ 2.17 moles.
Steps: 6
Show Steps
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.
