16. 2.362 g acid (Molecular weight 126) is reacted with 50ml NaOH (10 ml NaOH neutralizes 20 mL N/2 HCI). After the acid is completely reacted the solution is diluted to 250 mL. 10 mL of diluted solution consume 5 mL N/10
acid for neutralization. Calculate the basicity of acid. (Ans: 2)

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

Ab c or d ? i’m not sure what the answer is

Name atleast 3 type of energy associated with the microwave
