Calculate the displacement volume for a quantity of powder equivalent to the 250mg dose of drug X. If there is 250mg in each 5mL dose, 100mL has 20-times this – that is to say, 5,000mg. If 68mL is needed, it means 5,000mg displaces the remaining 32mL of water.
21 wrz 2022 · Calculations of volume-volume ratios are based on Avogadro's hypothesis. Pressures and temperatures of the gases involved need to be the same.
16 sie 2023 · Students use the water displacement method to find the volume of different rods that all have the same mass. They calculate the density of each rod and use the characteristic density of each material to identify all five rods.
3 cze 2021 · This article illustrates worked examples of calculation questions that involve the concept of displacement volumes and its implication when preparing injectable dosage forms.
21 cze 2016 · Spot the relationship between 5 and 30, 100 and 500 to find the values of x, y and z. Alternatively: So, 30 mg, 100 mg and 500 mg of diamorphine will displace, respectively, 0.36 mL, 1.2 mL and 6.0 mL of diluent. Displacement volumes may be used in calculations for different formulations.
Look at the graduated cylinders below. Then, record the volumes without and with. the object. Finally, using the formula Vf-Vi (final volume - initial volume) calculate the volume of each object. Remember to label units on your answers. Initial Volume (Vi) =________.
