Calculate the morality for the following
10.5 kg of Na2 SO4. 10H2O in 18.60 L

1.75M

Explanation:

The problem deals with finding the molarity of the given compound.

 The compound is:

             Na₂SO₄.10H₂O

Mass of the compound  = 10.5kg  = 10500g

Volume of the compound  = 18.6L

Molarity is the number of moles of solute in a solution;

     Molarity  =  

 Number of moles  =  

 Molar mass of   Na₂SO₄.10H₂O  = 2(23) + 32 + 4(16) + 10[2(1) + 16]

                                                       = 322g/mol

 Now;

    Number of moles  =   = 32.6mole

So;

  Molarity  =   = 1.75M

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
