Question

7)When 13.6g of unknown solute was added to 150g of
water (Tf=0°C, Kf = 1.86)the freezing point of the resulting
solution was recorded to -3°C, the molar mass (g/mol) of
the solute is:​

Answer 1

FNet = F1 + F2 + F3….

FNet = F1 + F2 + F3….FN is the force acting on a body. When the body is at rest, the net force formula is given by, FNet = Fa + Fg.
