The correct answer is 2.20 × 10⁻²⁸ kg

Mass defect for oxygen-16 = 0.13261 amu

1 amu = 1.66 × 10⁻²⁷ kg

Converting amu to kg we get,

0.13261 amu ( 1.66 × 10⁻²⁷ kg / 1 amu ) = 2.20 × 10⁻²⁸ kg

Thus the mass defect for oxygen-16 in  kilograms is 2.20 × 10⁻²⁸

<h2>Answer:</h2>

The correct option is B which is 2.20 × 10-28 Kg .

<h3>Explanation:</h3>

Given mass defect of oxygen is equal to  0.13261 amu .

Now the question is the mass defect of oxygen in kilograms.

amu is one of the unit of mass which is equal to the 1/12 of mass of an atom of carbon-12.

While 1 amu = 1.66 * 10-27 Kg

So

0.13261 amu =  1.66 * 10-27 Kg × 0.13261

                     =  22.01 × 10-29 or 2.201 × 10-28 Kg

So if we covert the amu to kilograms which means from small unit of mass to large unit of mass. The 0.13261 amu is equal to 2.20* 10-28 Kg

What property of a liquid is used when petrol, ( gasoline) is pumped from the tank to the engine of a car? I need answers!!!!
Romashka-Z-Leto [24]
In many modern cars the fuel pump is usually electric and located inside the fuel tank. The pump creates positive pressure in the fuel lines, pushing the gasoline to the engine. The higher gasoline pressure raises the boiling point.

What can you conclude from the figure shown?
arlik [135]

Answer:

A. Hund's rule has been violated

Explanation:

There must be one electron with the same spin in each orbital of the same energy before you can put two in the same orbital. In the photo, the 2s sublevel is completely filled before the 1s sublevel (if anything the 1s should have an up spin and down spin, with the 2s having one up spin).
