Answer 3

multiply the coefficients (2.04 *1.67) * (10^23 8 10^-24) = 3.41g

this should be right, because the total amount of particles in the system is 2.04 x 10^24 multipled by the mass of each should give you total system mass.

Answer 4

multiply the 2 numbers
10^23 * 10^-24 = 10^(23-24)

and 1.67 * 2.04

Answer 5
