Chemistry
1 answer:
Sergio [31]3 years ago
5 0

Answer:

Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat.  Conduction is the transfer of heat between substances that are in direct contact with each other. Thermal energy is transferred from hot places to cold places by convection. Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection. Heat can be transmitted through empty space by thermal radiation often called infrared radiation.

What is the molarity of a solution in which 102 grams of aluminum oxide, Al2O3, is
irga5000 [103]

Answer:

2.00 M

Explanation:

The formula mass of aluminum oxide is 2(27)+3(16)=102 g/mol.

So, there is 1 mole of solute in 500 mL=0.5 L of solution

Now, we can use the equation molarity = (moles of solute)/(liters of solution)

  • molarity = 1/0.5 = <u>2.00</u><u> </u><u>M</u>
