A student wishes to make a sample of insoluble salt, lead (II) chloride, in in the laboratory. Determine the mass of lead (II) chloride which could be made by reacting a solution containing excess lead (II) nitrate with a solution containing 23.4 g of sodium chloride

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

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.
