Q
Q: How many grams of NaOH are needed to prepare 0.5 moles of NaOH solution?
Solution:
The molar mass of NaOH is 40 g/mol. Therefore, to prepare 0.5 moles, you need 0.5 x 40 g = 20 g.
Steps: 5
Show Steps
Step 1: Find the molar mass of NaOH. The molar mass is 40 g/mol.
Step 2: Determine how many moles of NaOH you want to prepare. In this case, it is 0.5 moles.
Step 3: Multiply the number of moles (0.5) by the molar mass (40 g/mol).
Step 4: Calculate 0.5 x 40 g = 20 g.
Step 5: Conclude that you need 20 grams of NaOH to prepare 0.5 moles of NaOH solution.
