M=n(pie)/RT
n=osmotic pressure(1.2 atm)
M=molar of the solution
R=gas constant(0.0821)
T= temperature in kelvin 25+273
M=[1.2atm /(0.0821L atm/k mol x 298k)]=0.049mol L
M= moles of the solute/ litres of solution(250/1000)
0.049= y/0.25
moles of solute is therefore =0.01225mol
molar mass=33.29 g/0.01225mol=2.7 x10^3g/mol
<span>Since Electro Negativity will change their reactions the answer should be number 5. 12/6c and 13/6c. This is due to the fact that there is only one neutron difference between the two.</span>
Your blood is a living part or tissue of your body that composed of liquid and solid part. The liquid part is made of plasma and mineral like, water, salt and protein. While the solid part is composed of red blood cells, white blood cells and also platelets
