Question

The mass of one atom would best be measured in this unit:

OA) amu
OB) gram
OC) milligram
OD) microgram

Answer 1

mass of one atom is measured in the unit of 1 amu

Step-by-step explanation:

As we know that the mass of one atom is very small and it is of order of
`10^(-27)`

here we know that 1 amu is defined as 1/12 part of mass of 1 atom of C-12 isotope

so here we will have

`1 amu = 1.66 * 10^(-27) kg`

so here we can say that mass of one atom is measured in the unit of 1 amu
