Aload of bauxite has a density of 3.11 . if the mass of the load is 220. metric tons, how many dump trucks, each with a capacity of 11 cubic yards, will be needed to haul the whole load? (express your answer as an integer.)

Answer : The number of dump trucks required are, 8

Explanation : Given,

Density of load of bauxite =

Mass of load = 220 metric tons =

conversions used : 1 metric ton = 1000000 g

First w have to calculate the volume of load of bauxite.

Convert cubic centimeter to cubic yard:

So,

Volume of load =

Volume of load = 92.47 cubic yards

Now we have to calculate the number of dump trucks.

Capacity of a dump truck = 11 cubic yard

Number of trump trucks required =

Thus, the number of dump trucks required are, 8

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
