(a)
Interpretation:
For the given set of measurements the significant figures has to be determined.
Concept introduction:
Significant figures: The digits having a meaning in a given number are called as significant figures.
Significant figures – calculation rules
- Significant figure is a non-zero number (4443.2 has five significant figures)
- Zero’s placement in between non-zero number are significant figures (40005 has five significant figures).
- Zero’s before the non-zero number are not significant number (0.00040005 has five significant figures).
- Zero’s after the non-zero number are significant in case of that number contains decimal point (4.5000 has five significant figures).
- Zero’s after the non-zero number may or may not be a significant figure in case of that number does not have a decimal point (500 may have 1, 2 or 3 significant figures). In this cases use scientific notation to avoid ambiguity.

- A listing of a house for sale states that there are 5bedrooms, 4000 ft2 of living area, and a living room with dimensions 1718.5 ft. How many significant figures are there in each quantity? (Your answer may include the words ambiguous and exact.)arrow_forwardThe radius of an atom is on the order of1010 m. What is this radius in centimeters? In inches? In nanometers?arrow_forwardA sample of a bright blue mineral was weighed in air, then weighed again while suspended in water. An object is buoyed up by the mass of the fluid displaced by the object. In air, the mineral weighed 7.35 g; in water, it weighed 5.40 g. The densities of air and water are 1.205 g/L and 0.9982 g/cm3, respectively. What is the density of the mineral?arrow_forward
- Suppose you are trying to find the volume of a box based on the given measurements for the length, width, and height of the box, where the height was measured in two parts. length, l = 2.20 in width, w = 3.71 in height, h = 10.4 in + 1 in Calculate the height, ℎ, of the box, first keeping all digits, then rounding to the proper number of significant figures. unrounded h = ____in rounded h =____ in Calculate the volume (V) of the box using V =l x w x h. Round to the proper number of significant figures. v=_____in3arrow_forwardWhat is the thickness of a sheet of tin, measuring 75.0 cm long and 50.0 cm wide and weighing 4125 g? The density of tin is 7.28 g/mL. is the answer 0.151cm?arrow_forwardWhat is the density of lithium metal in g/cm3, if a cube measuring 0.82 cm x 1.45 cm x 1.25 cm has a mass of 0.794 g?arrow_forward
- The mass of a glass beaker is known to be 25.1 g. Approximately 5 mL of water areadded, and the mass of the beaker and water is measured on an analytical balanceto be 30.625 g. How many significant figures are there in the mass of the water?arrow_forwardA star is estimated to have a mass of 2 x 1036 kg. Assuming it to be a sphere of average radius 7.0 x 105 km, calculate the average density of the star in units of grams per cubic centimeter.arrow_forwardIf the area of one tile is measured to be 1.07 ft2, how many tiles do you need to redo the floor of a 10.1 ft x 12.07 ft bathroom? Write the answer in the correct number of significant figures?arrow_forward
- If a monolayer of stearic acid has a mass of 2.5*10^-5 g and occupies a surface area of 82 cm^2, what is the height of the monolayer, in cm? The density of stearic acid is 0.839 g/cm^3.arrow_forwardIn determining the density of a rectangular metal bar,a student made the following measurements: length,8.53 cm; width, 2.4 cm; height, 1.0 cm; mass, 52.7064 g.Calculate the density of the metal to the correct numberof significant figures.arrow_forwardthe question asks to convert it to Japanese yen, I did so and wasn't sure what the sig figs should come out to be, I figured it to be four sig figs because when finding the mass in grams, we multiply by 10.49 which has four sig figs and I carried it through to the end, reaching 2.1935x105 Japanese Yen.
