delta T = ikfm delta T is the amount f.p. is lowered. i is the number of particles; i.e., Na3PO4 will have i = 4 (3 for Na and 1 for PO4). m is molality. k is a constant and need not enter into the calculations. Arrange the

Compute delta(y) and dy for the given values of x and dx=delta(x) y=x^2 , x=8 , delta(x)=0.5 Delta(y)= ??? dy = ??? I got dy=8 by doing: dy= (f prime of x)dx dy=2xdx dy=2xdelta(x) dy=2*8*0.5 dy=8 but I have not clue how to find
