42. * EXTENDED RESPONSE A mole is a unit of Element Mass of smole measurement used in chemistry. The masses of one mole of three elements are in the table. Hydrogen 1.008 grams a. A 100 gram sample of ascorbic acid contains Carbon 12.011 grams 4.58 grams of hydrogen. To the nearest tenth, Oxygen 15.999 grams find the number of moles of hydrogen. b. A 100 gram sample of ascorbic acid contains 54.5 grams of oxygen. To the nearest tenth, find the number of moles of oxygen in the sample. e. The ratio of moles of hydrogen to moles of carbon in ascorbic acid is 4:3. How does this ratio compare with the ratio of moles of hydrogen to moles of oxygen in ascorbic acid? Explain.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

answer: apothems is your answer

step-by-step explanation: hope u get it right

the option best identifies the textual evidence that supports this conclusion is c.) when an argument is over, how many weighty reasons does a man recollect which his heat and violence made him utterly forget? in order to recognize textual evidence is to identify the topic sentence where the author states the main idea. textual evidence is what supports the topic sentence or main idea of a passage.
