EXPERIMENT 1: DENSITY OF A SUBSTANCE Data Sheet Table1: Isopropyl Alcohol Data Measurement Result Mass of 10 mL graduated cylinder (g): 33.5g Volume of alcohol added to graduated cylinder (mL): 10ml Mass of graduated cylinder and alcohol (g): 40.3g Mass of alcohol (g): 6.8g Calculated density of alcohol (g/cm3): Actual density of isopropyl alcohol: 0.790 g/cm3 Experimental error (use equation below):

2b2t

explanation:

2b2t

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )

i think its 5049.

i hope this !
