Polyethylene terephthalate (PET) is used in plastic water bottles. A water bottle has a mass of 14.0 grams. Given a density of 1.38 g/cm^3. what's the volume of the plastic used to make the water bottler in cmcm^3?

43.452

step-by-step explanation:

284 times .153 = 43.452

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
