Answer:

.91 ng

Explanation:

So for the first one the conversion factor which is the first blank in your first question is (1/100) and the second blank which would be (74)(1/100) is 0.0174

The second one would have two conversion factors where the first blank would convert to grams, so the conversion factor for the first blank is (1000/1), then converting from grams to nano grams, whose conversion factor is (1,000,000,000/1).

So in general the second one is 9.1 x 10^-13 (1000/1) x (1,000,000,000/1) = .91 ng

Hope my explanation is easy to understand.- Ryan Brown indy

9.1 x 10-¹³ kg is equal to 0.91 nanograms (ng).

CONVERT MASS IN kg TO g

  • Kilograms and grams are both interconvertible units of mass. The conversion ratio of kg to grams is as follows:

1000 grams = 1 kilogram

  • Hence, 9.1 x 10-¹³ kg is equal to (9.1 x 10-¹³ × 10³)

= 9.1 x 10^(-13+3)

= 9.1 × 10-¹⁰ grams.

CONVERT MASS IN g TO ng

  • The conversion ratio of grams to nanograms (ng) is as follows:

1gram = 1000000000 (10⁹) nanograms

  • Hence, 9.1 × 10-¹⁰ grams = 9.1 × 10-¹⁰ × 10⁹

= 9.1 × 10^(-10 + 9)

= 9.1 × 10-¹

= 0.91 nanograms (ng).

Therefore, 9.1 x 10-¹³ kg is equal to 0.91 nanograms (ng).
