() vancomycin, CoeHrsClNg024 Rank these compounds in terms of the mass percentage oxygen they contain. Assessment Criteria 12 culate mole quantities, relative atomic and relative formula masses (a minimum of 5 to be calculated). Cal What is Avogadro's number, and how is it related to the mole? Without doing any detailed calculations (but using a periodic table to give atomic nssserk the following samples in order of increasing number of atoms: 0.50 mol H2O, 16 g O2, 9.0×1023 molecules of H2O2. 3. Determine the number of moles (to 3 sig. figs.) present in each of the following: 2.3 g of sodium b a 0.32 g of O2 c 1.0 g of CH4 d 0.10 g of SO2 4.0 g of N2 f e 2·5 g of Na2CO3 g 15.6 g of CuSO4.5H20 2.7 g Fe203 i h 3.0 g (NH4)2SO4 A sample of the male sex hormone testosterone, C19H2802, contains 3.88x1021 hydrogen atoms. (a) How many atoms of carbon does it contain? (b) How many molecules of testosterone does it contain? (c) How many moles of testosterone does it contain? (d) What is the mass of this sample in grams?Explanation / Answer
1. Avogadro's number is defined as the number of atoms or molecules in one mole of a substance.
Avogadro's number is equal to 6.023 × 1023.
1 mol is equal to 6.023 × 1023
As per chegg guidelines, first question is answered.
