The answer is 5.4! I found it on a an online calculator!
Answer:
Part A:
First, convert molarity to moles by multiplying by the volume:
0.293 M AgNO3 = (0.293 moles AgNO3)/1 L x 1.19 L = 0.349 moles AgNO3
The correct answer is b, 18 protons
The atom that is made up of two protons is He. The number of neutrons is also two. The number of electrons matters in the charge. So to make 10 electrons, we add 8 more. hence, 4/2 He 8-.
The amount of product obtained in a chemical reaction. The absolute yield can be given as the weight in grams or in moles.
