Consider the following statistic. As of January 2009, the USA has produced 60,000 metric tons of nuclear waste in 60 years of operating 104 nuclear power plants.

On average, how much waste is produced by each plant on a monthly basis?
0.8 tons per month
83.3 tons per month
104 tons per month
866.3 tons per month

answer: mercury

explanation:

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
