Answer:

The 5.53 moles of virus in an oil tanker.

Explanation:

Given:

Mass of virus m = 9 \times 10^{-12} mg

Mass of oil M = 3 \times 10^{7} kg

From the formula of moles,

Moles of viruses is given by,

Mass of 1 oil tanker divide by mass of 1 mole of virus,

      = \frac{3 \times 10^{7} } {9 \times 10^{-12} \times 6.022 \times 10^{23} \times 10^{-6}   }

      = 5.53

Therefore, the 5.53 moles of virus in an oil tanker.

Explanation:QA: “What is ordinary glass made of ?”

Glass is mostly silica, or silicon dioxide, present as quartz in many types of sand. Pure silica forms a highly transparent glass, but has a very high melting or softening temperature, around 1700°C. Even at such high temperatures it is highly viscous and difficult to work. Its use is largely confined to applications requiring high transparency to ultra-violet and infra-red radiation, stability at elevated temperatures or low thermal expansion coefficient.

“Ordinary glass” windows and drinking vessels are typically made from soda-lime glass, containing silica with around 25% sodium, calcium and other oxides, which together reduce the softening temperature to roughly 500–600°C

A proton, which is the nucleus of a hydrogen atom, can be modeled as a sphere with a diameter of 2.4 fm and a mass of 1.67 10-27
Step2247 [10]
For the answer to the question above asking to d<span>etermine the density of the proton. 
</span>Density is mass over volume. 

The volume of a sphere is 4πr³/3. r is half the diameter. 

So the density would be 2.3×10¹⁷ kg/m³. 
I hope my answer helped you. Feel free to ask more questions. Have a nice day!
