Consider two isotonic solutions at same temperatures. The solute in the solution A has the molecular mass M and the solute in the solution B has the molecular mass 2M. If the volume of both the solution is same; then, which of the following statements is correct?
The number of the moles of solutes in A and B are same.
The mass of the solute in A and B is same.
The number of the moles in solution A is double the number of the moles in solution B.
The number of the moles in solution B is double the number of the moles in solution A.
oh yeah
all elements are artificially prepared .--true/false
STATE AND EXPLAIN THE LARGE SCALE USE OF THE PROCESS OF SEDIMENTATION AND DECANTATION ?
PLS ANSWER MY QUESTION FAST TOMORROW I HAVE TO SUBMIT.
what are elements?
why is handpicking the most common way of seperatin mixtures?
give some example for mixtures
pls

Elaborate
is the sublimation printer like other printers?
if not what makes them different and where are they used?
:)
Please explain the diagram in the chapter separation of mixture showing fractional distillation.
why is cuttin a treea chmical change
