Question

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 answers have the correct number of significant digits. How many moles of viruses have a mass equal to the mass of an oil tanker?Round your answer to 2 significant digits.

Answer 1

To calculate the number of moles of viruses with a mass equal to the mass of an oil tanker, we need to convert the masses to grams and then use the formula moles = mass / molar mass.

Step-by-step explanation:

To calculate the number of moles of viruses with a mass equal to the mass of an oil tanker, we need to first convert the mass of the virus and the mass of the oil tanker to grams. The mass of the virus is given as 9.0 x 10^-12 mg, which is equal to 9.0 x 10^-9 g. The mass of the oil tanker is given as 3.0 x 10^7 kg, which is equal to 3.0 x 10^10 g.

Next, we need to calculate the number of moles for each mass. To do this, we use the formula:

moles = mass / molar mass

The molar mass of a virus depends on the type of virus, so we can't calculate it without more information. Once we have the molar mass of the virus, we can calculate the number of moles for each mass and compare them.
