Question
9. Liquid X floats on top of liquid Y, as shown in the graduated cylinder to the right Suppose liquid Z has a density of 3.8 g/mL, measured to 2 significant figures. Assuming Liquid Z does not mix with the other liquids, Liquid d = 1.03 g/mL (liquid X) (A)...will float above Liquid X. (B)...will float above Y but be below X. (C) ...will sink below Liquid Y (D) ...will be above Y, but may be above or below X. (E) will be below X, but may be above or below Y. d 3.82 g/mL (liquid Y) 10. Which of the following contains the largest number of S atoms? (A) S (B) 11 S02 (C) 5 S20 (D) 7 NazS0 6.626×10-34 kg-mT × 2.2 s 2.51 kg x 1.5.107 11. What are the units from the following calculation? - 51kg 7 (B) m (C) m/st (D) s/m (E) kg?m/sExplanation / Answer
10) d 7 Na2S04 CONTAIN LARGEST NO OF ATOMS
, just need moles of atoms. 7 * 6 = 42 moles atoms.
