Question

The particle of dust has a mass of 7.53×10^-10 kilograms. Find the weight of 5 billion dust particles.


Plzzz help !!

Answer 1

\[5.0 \times 10^{9}particles \times \frac{ 7.53 \times 10^{-10}kg }{ 1 particle } \]

Answer 2

That will give you weight in kg. If you need it in something else, you need to convert kg to that something else

Answer 3

@Larryboxaplenty so I'll be dividing 7.53×10^-10 by 5,000,000,000?

Answer 4

You multiply the mass of one particle by 5 billion. The one is there so show that the unit "particles" cancel
