Describe a method to determine the mass of dissolved solids ina 100 cm 3 sample of river water.

Physics students use a spring scale to measure the weight of a piece of lead. The experiment was performed two times, one in air and the other in water. If the volume of lead is 50 cm3, what is the difference between two readings on the scale? Density of water is equal to 1000 kg/m³Group of answer choices500 N0.5 N5 N50 N

Match the following word pairs concerning the use of graduated and volumetric pipettes.Group of answer choicesThe volume level must be read in reverse (e.g. a liquid filled to 8.6 mL delivers 1.4 mL).The glassware can only deliver one exact volume.Requires pre-rinsing before useCare should be taken to avoid solution entering the pipette filler

In an experiment to determine the density of plasticine, a student records the mass m and the volume V of a range of differently-sized samples. These readings areplotted on a graph as shown. Determine the gradient G of the line and hence the density ρ of the plasticine using the equation ρ = 1/G. Enter your value for ρ to 3 s.f. in the space provided below, ignoring the unit (g/cm^3).

Which is a better estimate for the volume of a plastic cup? 20 pints   20tablespoons
