Question
Rank the following samples in number of hydrogen atoms,from least to greatest. Your response should be a fourletter "word" made up of the letters a, b, c and d. For example, ifyou think a contains the least number of hydrogen atoms, followedby b, c and d (the most), your response should be the word abcd(lower case, no spaces, no commas).a) 4 moles of C4H10
b) 3.5 moles of C6H12
c) 2.5 moles of C8H18
d) 3 moles of C7H16 Rank the following samples in total number of atoms,from least to greatest. Your response should be a fourletter "word" made up of the letters a, b, c and d. For example, ifyou think a contains the least total number of atoms, followed byb, c and d (the most), your response should be the word abcd (lowercase, no spaces, no commas).
a) 0.5 moles of Cl2
b) 17 g of NH3
c) 22 g of CO2
d) 18 g of H2O

Explanation / Answer
for question 1 a) 4 moles of C4H10 1 mole ofC4H10 = 10 hydrogen atoms. so 4 moles C4H10 = 4*10 hydrogen atoms = 40 hydrogen atoms. b) 3.5 moles of C6H121 mole ofC6H12 = 12 hydrogen atoms. 3.5 moles C6H12 = 12*3.5 hydrogen atoms = 42 hydrogen atoms c) 2.5 moles of C8H18 1 mole of C8H18 = 18 hydrogenatoms so 2.5 moles of C8H18 = 18*2.5hydrogen atoms = 45 hydrogen atoms d) 3 moles of C7H16 1 mole of C7H16 = 16 hydrogen atoms so 3 moles of C7H16 = 16*3 hydrogen atoms = 48 hydrogen atoms so a is smallest followed by b , c and then d being thelargest so answer is abcd for question 2 a) 0.5 moles of Cl2 1 mole of Cl2 = 2*6.023*1023 atoms = 1.2046 x 1024 atoms 0.5 moles of Cl2 = 0.5 * 1.2046 x 1024atoms = 6.023 x 1023 atoms b) 17 g of NH317 gm implies 1 mole so 4*6.023*1023 atoms. c) 22 g of CO244 gm of CO2 = 3*6.023 x1023 atoms so 22 gm CO2 = 3*6.023 x 1023 /2 = 9.0345 x 1023 atoms. d) 18 g of H2O 18 gm gives 1 mole = 3* 6.023 x 1023 atoms so a is smallest followed by c, d then b being the largest so answer is acdb
