TEQuantifying compositions is important to understanding materials. While we were talking about elements and the periodic table in class, we mentioned molecular weight (mass) and moles. This problem is to encourage you to refresh your memory about moles and molecular mass. Vitamin C, or ascorbic acid, has a chemical formula of CoH&Oo. (A) You have some quantity of Vitamin C, which happens to contain one mole of oxygen. How many moles of hydrogen does this contain? How many moles of Vitamin C do you have? (B)A typical multivitamin contains 1000 mg of Vitamin C. If each vitamin tablet is 2.5 g, what mass of tablets would be needed to contain a mole of vitamin C? Now, extend your understanding of moles beyond elements: (C)lf you have a mole of football, how many footballs do you have?

Please add states of compound as well thank you
#13 for the column, change in composition -- you must choose from the drop down menu "go up, go down, not change" Thanks!
for part a) can someone show how we get from 35265405 moles to 564.24tonne/year
is the A:B ratio just a place holder for the unknown compound can you use other variables in place of "A and B" also would H2O work as another formula instead of Na2O
predit the products - please answer with drawings!
I want the best value for percent purity and how did you arrive at the best value
General formula of a polymer is-(CH2CHCHCN)n-, where n is typically greater than 10,000. Then take a sample of this polymer weighs 755.9 g and contains 3.112 x 1020 molecules of -(CH2CHCHCN)n-, so calculate n?

Orciprenaline(C11H17N03,211.258 g/mol) is a bronchodilatorused in the treatment of asthma.The BP assay for orciprenalinetablets is described below. Read thefollowing information carefully andanswer the questions below.(Record your answers in decimalnotation to the indicated significantfigures OR decimal places)ASSAY - 20 tablets weighing 2.597 gwere crushed to a powder. Aportion of the crushed powder(0.5456 g) was shaken with 50 mL of0.1 M HI, the mixture was filteredand made up to 100 mL. 10 mL ofthis solution was further diluted to100 mL with 0.1 M HCI. Themeasured absorbance of thediluted solution at 276 nm was0.582. Additional information: A1%72.3, stated content = 20 mg Calculate:a) The concentration oforciprenaline in the diluted solutionin mg/L b) The actual amount oforciprenaline (in mg) in the powderassayed.c) The actual amount oforciprenaline (in mg) per tablet.d) The percentage of stated contentof per tablet.

Hi, I found the data in the attached table. The question I am struggling with is attached as well. Particuarly, the last sub-question, part C, which is about what happens to the hydrate formula if the copper sample (or crucible) is "wet" rather than "dry." I think that the hydrate formula would increase from 2 to 3, but could you confirm and explain what steps I would take to know this for sure? Thank you
