Answer:
<em>6960000 Nickel atoms</em>
<em></em>
Explanation:
radius = 125 pm = 125 x 10^-12 m
diameter of each atom = 125 pm x 2 = 250 pm = 250 x 10^-12 m
span of distance to be achieved = 1.74 mm = 1.74 x 10^-3 m
number of nickel atoms = (1.74 x 10^-3 m)/(250 x 10^-12 m) = <em>6960000 Nickel atoms</em>
Density is measured by
"<span>
the mass per volume of an object" or option B. Mass is measured by the amount of weight in a object. (option A) The amount of weight is measured by the size of the object, (option C) and the size of the object is often measured by the hardness of an object. (option D)
