Answer:N=1151724138 atoms
Explanation:The atomic radius of molybdenum atom is 145 picometers so lining up molybdenum atoms is like lining up the beads of radius 145 picometers
so one bead would cover the length of 145*2=290 picometers
hence the atom's diameter =D=290 picometers
D=290 *10^(-12)
also
Distance span= 33.4 cm
Distance span= 0.334m
As the Distance span adds up with no of atoms the resulting formula is
Distance span by atoms= No of atoms * atom's diameter
so
Answer:
C. a computer
Explanation:
Quantitative data are measures of values or counts and are expressed as numbers. The best tool out of all shown to deal with a large amount of numerical data is a computer
