Describe how to make 90ml of a 2M NaCl solution. The molecular weight (MW) of NaCl is 58.44g/mole. Show your calculations and mention any equipment used in the measuring/making process.

Alpha particles have positive charge, beta particles have negative charge, and answer 4 just doesn’t make sense. thus, you are left with only one possible answer.
