Assume it is 1 litre and weighs 1kg.
2 percent of 1 kg is 20g.
20g divided by molar mass of NaOH.
20g divide by 40 = 0.5 mole
0.5 mole in a litre would be 0.5M
That is the answer: 0.5M
Answer:
It is easier for sound waves to go through solids than through liquids because the molecules are closer together and more tightly bonded in solids.
