After addition or subtraction, theanswer cannot have more digits to theright of the decimal point than any ofthe original numbers.After determining the appropriate number ofsignificant figures, round off your final answer.Express your answer in kilograms using the appropriate number of significant figures.View Available Hint(s)1. If the first digit you drop is greaterthan or equal to 5, add 1 to the lastdigit you keep. You are rounding up.2. If the first digit you drop is less than 5,do nothing to the digits you keep. Youare rounding down.kgPart BAn unknown object is placed on a balance, which then reads 6.118 g. Its volume is measured to be 3.04 cm³.

Calculate the average density of a single Al-27 atom by assuming that it is a sphere with a radius of 0.143 nm. The masses of a proton, electron, and neutron are 1.67261024g,9.10941028g, and 1.67491024g, respectively. The volume of a sphere is 4r3/3, where r is its radius. Express the answer in grams per cubic centimeter. The density of aluminum is found experimentally to be 2.70 g/cm3. What does that suggest about the packing of aluminum atoms in the metal?

The planet Zoltan is located in a solar system in the Andromeda galaxy. On Zoltan, the standard unit for the amount of substance is the wog and the standard unit for mass is the wibble. The Zoltanians, like us, chose carbon-12 to define their standard unit for the amount of substance. By definition, one wog of C-12 atoms contains 2.50 x 1021 atoms. It has a mass of exactly 12 wibbles. What is the mass, in wibbles, of 1 wog of nitrogen atoms? What is the mass, in wibbles, of 5.00 x 10-1 wogs of O2? What is the mass, in grams of 1 wog of hydrogen atoms? Expert Solution
