SUMMARY

This discussion focuses on calculating the grams of solute required to prepare specific solutions: 100 mL of 0.1 N Ca(OH)2 and 100 mL of 5% NaCl. For the 0.1 N Ca(OH)2 solution, the calculation involves using the molecular weight of 74 g/mol to determine the equivalent weight and subsequently the grams needed. For the 5% NaCl solution, it is confirmed that 5 grams of NaCl is required for 100 mL, based on the definition of percentage concentration.

PREREQUISITES
  • Understanding of normality and molarity in solutions
  • Knowledge of molecular weight calculations
  • Familiarity with percentage concentration definitions
  • Basic chemistry concepts related to solute and solvent
NEXT STEPS
  • Learn how to calculate grams of solute for different normality levels
  • Study the concept of equivalent weight in chemistry
  • Explore the preparation of solutions with varying concentrations
  • Investigate the differences between molarity and normality
USEFUL FOR

Chemistry students, laboratory technicians, and anyone involved in solution preparation and concentration calculations.

Please help me with this:

Calculate how many grams of solute are necessary to prepare:
1) 100 mL of 0.1 N (Normal Solution) Ca(OH)2 (molecular weight = 74)

2) 100 mL 5% NaCl (molecular weight = 40)

What have you tried so far and where are you getting stuck?
 
I know how to find the solute of Molarity of solution, but I don't know how to find the grams of solute for Normal Solution. I've never done this type of question, and I can't find the formula to find it.

As for question 2, I I know that a solution is 1% when it contains 1 gram of solute per 100 mL of solution. The question is 100mL of 5% NaCl. Does that mean that there is 5 grams of solute? Is there a formula for solving this type of problems?
 
A 0.1 Normal solution contains 0.1 moles of solute per liter of solution.
