A virus has a mass of 9.0 x 10^-12 mg and an oil tanker has a mass of 3.0 x 10^7 kg. Use this information to answer the questions below. Be sure your answer have the correct number of significant digits. How many moles of viruses have a mass equal to the mass of an oil tanker?

Respuesta :

Answer:

The 5.53 moles of virus in an oil tanker.

Explanation:

Given:

Mass of virus [tex]m = 9 \times 10^{-12}[/tex] mg

Mass of oil [tex]M = 3 \times 10^{7}[/tex] 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,

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

      [tex]= 5.53[/tex]

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