What is the freezing point, in °C, of a 1.56 m aqueous solution
of K3PO4?
Note: K for water is 1.86 °C/m
Enter rounded answer to three decimal points.

1,380 °C hope this is the right answer

your answer would be a. 12.5 kg

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
