A 2.40-g sample of an unknown enzyme is dissolved in water to make 7.10-mL of solution. What is the molar mass of the enzyme if the osmotic pressure of the solution at 37 degrees Celcius is determined to be 0.335 atm

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.

Isec i will do it and them i will let you know

The ratio is 3: 2. i.e. c.

The answer is c.  h+  and oh−  react to form water (h2o). i just took the test and i got it right. hope this !
