Chemistry Essentials QuizVersión en línea Core topics recap por Owen Blankenfeld 1 How many significant figures are in 0.02050 g? a 3 significant figures b 2 significant figures c 4 significant figures d 5 significant figures 2 How many significant figures are in 120 mL? a 3 significant figures b 1 significant figure c 4 significant figures d 2 significant figures 3 What conversion factor is used to convert 0.750 liters to milliliters? a 100 mL / 1 L b 1 L / 1000 mL c 1000 mL / 1 L d 10 mL / 1 L 4 Why is density considered an intensive property? a Because it is a weight measure b Because it does not change based on the amount of matter present c Because it changes with volume d Because it depends on mass only 5 A student measures 25.0 mL, 25.1 mL, and 24.9 mL. The true value is 30.0 mL. Are the measurements accurate and/or precise? a Accurate but not precise b Precise but not accurate c Neither accurate nor precise d Both accurate and precise 6 What is (2.50 × 10^2) × (4.00 × 10^-5)? a 1.00 × 10^1 b 1.00 × 10^2 c 1.00 × 10^0 d 1.00 × 10^-2 7 A student calculates copper’s density as 8.42 g/cm^3. The accepted value is 8.96 g/cm^3. What is the percent error? a 3.2% b 11.6% c 6.03% d -6.03% 8 An object has mass 26.5 g and displaces water from 15.0 mL to 21.0 mL. What is its density? a 1.75 g/mL b 0.43 g/mL c 21.0 g/mL d 4.4 g/mL 9 According to the Law of Conservation of Mass, if 24.3 g Mg reacts with 16.0 g O, what is mass of MgO produced? a 60.3 g b 24.3 g c 10.3 g d 40.3 g Feedback 1 Significant figures are the digits that carry meaning in a measurement; trailing zeros after decimal are significant. 2 Without a decimal point, trailing zeros may not indicate precision. 3 There are 1000 mL in 1 L. 4 Intensive properties do not depend on sample size. 5 Values are close to each other (precise) but far from the true value (not accurate). 6 Multiply coefficients: 2.50×4.00=10.00; powers add to 2-5 = -3; result 1.00×10^-2. 7 Percent error = \|experimental - accepted\| / accepted × 100%. 8 Density = mass / volume; volume = 21.0-15.0 = 6.0 mL. 9 Mass is conserved in chemical reactions.
