    So the question is basically if one dust particle= 7.53x10^-10kg then 5 billion dust particles would be?

    You know how much one dust particle weighs (masses, actually). You want to find the mass of 5,000,000,000 of them. Multiply the unit mass (mass of 1 dust particle) by the number of dust particles. Do you know how to multiply numbers when one is in scientific notation (the mass) and one is not (the number of particles)?
