Stoichiometry A long cylinder and a sphere both of 5 cms diameter are made from the same porous material. The flat ends of cylinder are sealed. Both the cylinder and sphere are saturated with the same solution of sodium chloride. Later both the objects are immersed for a short and equal interval of time in a large tank of water which is well agitated. The fraction of salt remaining in the cylinder and the sphere are Xc and Xs respectively. Which of the following statement is correct? Xc > Xs Xc < Xs Xc = Xs Xc greater/less than Xs depending on the length of the cylinder Xc > Xs Xc < Xs Xc = Xs Xc greater/less than Xs depending on the length of the cylinder ANSWER DOWNLOAD EXAMIANS APP
