Question

calculate the number of moles and molecules of Urea present in 5.6 gram of urea​ N2H4CO​

Answer 1

Answer:

The number 6.022×1023 is known as Avogadro's number. Thus, the number of moles of urea present in 5.6 g of urea are 0.0933 mol. Thus, 0.0933 mol urea contains 0.3732 mol of hydrogen. Thus, 5.6 g of urea contains 2.247×1023 atoms of hydrogen
