Justify the scientist’s answer, not merely citing the rule, hut explaining it.arrow_forwardA proton has a radius of approximately 110-13 cm and a mass of 1.71024 g. a. Determine the density of a proton. For a sphere, V=(4/3)r3;1cm3=1mL;=3.14. b. By assuming that black holes have the same density as protons, determine the mass (in kilograms) of a black hole and the size of a sand particle. A typical sand particle has a radius of 1104 m.arrow_forward
- 1.90 A calibrated flask was filled to the 25.00-mL mark with ethyl alcohol and was found to have a mass of 19.7325 g. In a second experiment, 25.0920 g of metal beads were put into the container and the flask was again filled to the 25.00-mL mark. The total mass of the metal plus the alcohol was 43 .0725 g. Describe how to determine the density of the metal sample.arrow_forward1.84 A student was given two metal cubes that looked similar. One was 1.05 cm on an edge and had a mass of 14.32 grams; the other was 2.66 cm on a side and had a mass of 215.3 grams. How can the student determine if these two cubes of metal are the same material using only the data given?arrow_forwardWhat is the mass of a 43.8-mL sample of gasoline, which has a density of 0.70 g/cm3?arrow_forward
