C3H2N, 208.19 g/mol chemical formula?
slava [35]
First, determine the molar mass of the empirical formula given for the substance. This can be solved by adding the products of the number of moles and the molar mass of each of the atom as shown below,
 
         M = (3 mols C)(12 g C/1 mol C) + (2 mols H)(1 g H/1 mol H) + (1 mol N)(14 g N/1 mol N)
         M = 52 g/mol

Then, divide the given molar mass above by the calculated value.
       n = 208.19 g/mol / 52 g/mol = 4 

Then, multiply the value of n to the coefficients of the atoms giving us the answer.

Why is the combined cycle power generation system so much more efficient that the straight steam cycle?
rewona [7]

Answer:

  Because it uses the residual energy of the fluid used by the first engine.

Explanation:

  A combined cycle power generation counts with two heat engines that work in tandem from the same source of heat. The engines turn the energy into mechanical energy.

  The cycle is much more efficient than the other, almost 60% more.

  I hope this answer helps you.
