The goal of Lab 6 Unknown Titration and Molarity is to determine the molarity of an NaOH solution of unknown molarity by titration with an oxalic acid standard solution. You are given a NaOH solution and a vial of solid oxalic acid, H2C2O4•2H2O. Unknown # of NaOH 3 Given: 1L = 1000 mL Determine the concentration of the standard solution of H2C2042H20, oxalic acid dehydrate?

answer; i believe the correct answer is (c) /// is a homogeneous mixture of gaseous substance nitrogen,oxygen and smaller amounts of other substancesmixtures can be either ( homogeneous or heterogeneous)plz check first good luck

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
