Question
Which volume measurement is expressed in four significant figures? 5.50 mL 660 mL 6, 6 mL. 6600 ml. An 8.24-gram sample of hydrated heated until it has a constant it has constant mass of 6.20, grams. What was the % by mass contained in the original sample? 14.1% 24.8% 32.9% 75.2% A chemist analyzed a sample of copper (II) sulfate pentahydrate for water of hydration by weighing the hydrate, heating it to convert it to anhydrous copper (II) sulfate, and then weighing the anhydride. The hydrated sample was found to contain 30% H_2O The theoretical value is 33%. What is the percent yield? 91% 81% 85% 100% A steel cube is measured and found to be 9 cubic cm. What is the density of the cube i g/cm^3 if it has a mass of 141.8 g? 0.0213 5.25 C 0635 15.8 The graph below represents a uniform cooling of a substance, starting with the subset as a gas above its boiling point. During which transition(s) would boiling be Between E and F Between B and C Between C and D Boiling cannot occur.Explanation / Answer
1) In the given problem volume measurement which is in four significant figure is
=>6600 ml
this is because it has two trailing zeros which are significant and two sixes which are also significant hence it is the correct answer:)
