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.
3 cze 2021 · First calculate the single dose for this child in mg, 60mg/kg so 60mg x 37kg = 2220mg daily. This dose will be divided into four equal doses so 2220mg/4 = 555mg in each single dose. The next step is to determine what volume contains a dose of 555mg.
Answer. Step 1: Write the balanced equation for the reaction. 2Na (s) + H 2 O (l) → 2NaOH (aq) + H 2 (g) Step 2: Calculate the number of moles of sodium. Number of moles 0.0652 moles (to 3s.f.)
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.
18 lip 2015 · Displacement Value can be defined as the volume of drug that displaces 1 gram of suppository base. The most commonly used suppository base is Coca Butter or Theobroma oil.
Use this formula to calculate thickness: \(\mathrm{thickness=\dfrac{volume}{area}}\) To find the volume, you would rearrange the density formula. \(\mathrm{volume=\dfrac{mass}{density}}\)
21 wrz 2022 · The volume ratios above can easily be used when the volume of one gas in a reaction is known, and you need to determine the volume of another gas that will either react with or be produced from the first gas. The pressure and temperature conditions of both gases need to be the same.
