How can you express the solution in percent by volume?
Per cent by volume means mls of solute per 100 mls solution. So you need to know the volume of the solute and the total volume of the solution. Divide volume of solute by volume of solution and multiply by 100 to get per cent by volume.
What is the percentage of volume?
Volume percent (v/v %) is defined as: volume percent = [(volume of solute) / (volume of solution)] x 100% Volume percent is handy when preparing solutions of liquids. Concentration of a solution can be stated in volume percentages. Be aware that volume of solution is in formula denominator, not volume of solvent. Thus to get 10% v/v solution of ethanol in water you can take 10 ml of ethanol and add enough water to have total 100 ml of resulting solution. It is worth to mention volumes of solute and solvent cannot be simply added to get volume of solution. For instance if you add 10 ml of ethanol to 90 ml of water the volume of the solution will be less than 100 ml.
How do you make a 3 percent solution from a 40 percent solution?
This depends on the volume of the 40 percent solution you have. The question can be rewritten as: 40%a/(a+b) = 3% where a is the volume of the 40% solution, and b is the volume of water we need to add. Multiply both sides by (a+b) to get: 40%a = 3%a + 3%b Subtract 3%a from both sides to get 37%a = 3%b Divide by 3% to get: 12.3333...a = b Thus whatever the current volume is, you need to add 12.33333 times that volume in water in order to get a 3% solution.
What volume of a 2 percent Clindamycin solution can be made from 12 gm of Clindamycin powder?
To calculate the volume of a 2% Clindamycin solution, we need to know the density of the powder. Different formulations of Clindamycin powder may have different densities. Once we have the density, we can divide the mass of the powder (12 g) by the density to obtain the volume of the solution. The equation is: Volume (mL) = Mass (g) / Density (g/mL).
How do you calculate the capacity of a rectangle?
A rectangle is a 2-dimensional shape. Therefore, it has no volume - which is what capacity measures.
