Question

How do you find out the mass of 6 billion dust particles, if a dust particle has a mass of `7.53 xx 10^-10` g?

Answer 1

Six billion dust particles would have a mass of `7.53xx10^(-1)` g.

Explanation:

Multiply the number of dust particles by the mass of each dust particle.

`(7.53xx10^(-10)"g")/cancel"dust particle"xx(1.00xx10^9cancel "dust particles")=7.53xx10^(-1) "g"`
