Which of the following chlorine to oxygen mass ratios is possible for a different chlorine-oxygen compound? A) 1.000 B) 1.214 C) 2.428 D) 4.437 E) 5.014 Ratio of Cl:O mass ratios in the two compounds must be a ratio of small whole numbers. Only D (4.437/1.109 = 4.001) gives a small whole number ratio. vii) Typically, the mass of an atom, in grams is closest to A) 10 -32 B) 10 -22 C) 10 -10 D) 1 E) 10 23 Typical atomic mass 1- 200 amu, say 10. 10 amu x 1 g/6 x 10 23 amu) = 1.6 x 10 -22 g viii) There are two naturally occurring isotopes of silver that exist in approximately equal proportions. One of these is 107 Ag. Which of the following must be the other? A)
