Question

glassware used for
1. Preparation of 1% NaCl solution (1g NaCl in 100 ml solution)
​

Answer 1

Answer:

We know this by looking at the periodic table. The atomic mass (or weight) of Na is 22.99, the atomic mass of Cl is 35.45, so 22.99 + 35.45 = 58.44. If you dissolve 58.44g of NaCl in a final volume of 1 liter, you have made a 1M NaCl solution, a 1 molar solution.
