- Express the measurements to the requested number of significant figures. (a) 96,485 J/C to three significant figures (b) 2.9979 g/cm3 to three significant figures (c) 0.0597 mL to one significant figure (d) 6.626 1034 kg to two significant figuresarrow_forwardSuppose 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, 7 = 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. Calculate the volume (v) of the box using ?=?×?×ℎ. Round to the proper number of significant figure.arrow_forwardSuppose 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.

- A vernier caliper was used for taking the diameter of a sphere of unknown material. The radius measured is 1.70 cm and the mass of the spherical object is 150 grams. If the density of iron is 7.874 g/cm³ and your goal is to check your measurement accuracy, what is the percent error between the calculated density and the standard density of iron? A ruler and a vernier caliper were used to take measurements on a rectangular block. If the ruler measured 10.5 cm while the caliper shows 10.55 cm, what is the percent difference between the values? A vernier caliper was used for taking the diameter of a sphere of unknown material. The radius measured is 2.56 cm and the mass of the spherical object is 150 grams. If the density of iron is 7.874 g/cm³, is the sphere made out of iron? A vernier caliper was used for taking the diameter of a sphere of unknown material. The radius measured is 2.56 cm and the mass of the spherical object is 150 grams. What is the density of this object in g/cc?arrow_forwardWhat is the answer of following calculation using the proper number of significant figures? 34.876 + 12.5 = ? a. 47.3760 b. 47.376 c. 47.38 d. 47.4arrow_forwardWhat answer should be reported with the correct number of significant figures, for the following calculation? (12.87 + 3.7)/5.247arrow_forward
- Titanium is used in airplane bodies because it is strong and light. It has a density of 4.55 g/cm^(3). If a cylinder of titanium is 7.75 cm long and has a mass of 153.2 g, calculate the diameter of the cylinder. (V = pi*r^(2)*h, where V is the volume of the cylinder, r is its radius, and h is the height.)arrow_forwardWhich of the following options has the most significant figures? 07.8745 659.09 27497.3 0.74921arrow_forwardHow many significant figures should there be in the answer to the following calculation? (29.2 - 20.0)(1.79x10^5)/1.39arrow_forward
- If 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_forwardWhat is the answer for the following calculation to the correct number of significant figures? 3.1997 * 4.299x 10-8arrow_forwardI think I did a calculation wrong but I am having trouble understanding significant figures. In this problem, I am calculation the density of water from my previous calculations mass= 7.359g and volume=7.8mL. So I then divided 7.359g by 7.8mL to find density and got (.9434615385) on my calculator which I then turned into (.94) because I believe there should be 2 significant figures. Is (.94) correct or should 1.4 be the final answer?arrow_forward
