For the conversion of 0.0003140 kilograms to ounces, the conversion factors are 103 grams per kilogram, 1 pound per 453.6 grams
Ksenya-84 [330]

The correctly expressed answer is  1.108 × 10⁻² ounces.

<u><em>Explanation</em></u>

The conversion factors are 10³ grams per kilogram, 1 pound per 453.6 grams and 16 ounces per pound.

So, 0.0003140 kilograms = (0.0003140*10^3)grams = 0.3140 grams

Now, 1 pound = 453.6 grams

⇒ 1 gram = (\frac{1}{453.6}) pound

So, 0.3140 grams = (0.3140* \frac{1}{453.6})pound

Now,

(0.3140*\frac{1}{453.6})pound\\ \\=(0.3140*\frac{1}{453.6}*16 )ounces\\ \\= 0.01108ounces\\ \\= 1.108*10^-^2 ounces

So, 0.0003140 kilograms = 1.108 × 10⁻² ounces.
