12.47 g of ammonium nitrate are dissolved in water, then diluted to 250 ml. what is the molarity of the resulting solution?

= 0.6224 M

Molarity is given by the formula;

Molarity = Number of moles/Volume

But moles = mass/Molar mass

Thus;

Moles = 12.47 g/80.043 g/mol

          = 0.1556 Moles

Therefore;

Molarity = 0.1556 moles/0.25

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.
