A student used lab equipment to determine the density of a metal cylinder. The student obtained the following data. Massive metal, 47.208 g, the initial volume of water and a graduated cylinder, 15.6 ml, and volume level after adding metal sample to water 17.4 ML. Step 1: determine the volume of water displaced by the solid sample.

Step 2: determine the density of the metal sample and input the answer, rounded to proper significant figures, in the submission box for this question.

no but i do not usually comment or use my voice that much when it comes to social media

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

cu2o

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
