9. The smallest living organism discovered is the mycoplasm. Its mass is 1.0*10-16g.Express the mass ina. petagramsb. femtogramsc. attograms10-16=-41:0 X-4=4#9

mass = 1 x 10^-16
1 petagram = 1 x 10^-15 grams
multiply the mass by 1x10^-15
1x 10^-16 1x 10^-15 = 1 x 10^-31
1 femtogram = 1x10^15
Multiply the mass by 1x 10^15
1 x 10^-16 * 1 x 10^15 = 1 x 10^ -1
1 Attogram = 1 x 10^18
Multiply the mas by 1 x 10^18
1 x 10^-16 * 1x10^18 = 1 x 10^-2
