A student uses a device to measure a string. The units reported on the device are haggards, hg, and he measures the string to be 14.9 haggards. Using the following conversion factors, report the measurement in centimeters. 1hg = 2.3 zazzles: 1farb = 3.2 zazzles; 9.1 cm = 1 farbs

58750.08068 is the answer i think

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
