Calculate the molar mass of NH4NO3.
molar mass of NH4NO3 =
g/mol

67g/mol

Explanation:

The given compound is:

          NH₄NO₃ :

Problem here is to find the molar mass of the compound.

 Now;

The molar mass is the sum of the atomic masses of the elements in the compound.

   Atomic mass of N  = 14g

   Atomic mass of H  = 1g

   Atomic mass of O  = 16g

So;

   Molar mass = 14 + 4(1) + 1 + 3(16) = 67g/mol

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

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.
