Question #7169

the osmotic pressure of a solution is 3.2,which contains 45gm of sucrose in per liter of solution in 20 degree celcius calculate R

Expert's answer

PV=nRT

R=PV/nT

P=3.2

T=273+20=293

n=m/Mw=45/342=0,1315

v=1

l

R=3.2*1/293*0.1315=0.0830

R=PV/nT

P=3.2

T=273+20=293

n=m/Mw=45/342=0,1315

v=1

l

R=3.2*1/293*0.1315=0.0830
