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?

The 5.53 moles of virus in an oil tanker.

Explanation:

Given:

Mass of virus mg

Mass of oil 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,

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

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.
