How do you get a 10 percent solution from a 95 percent solution?
If you mean: % by MASS ( %m/m), it's quite easy to do (based on the 'Mass Conservation Law).Measure 10 gram of the 95%m/m original solution, this contains 95% of 10g = 9.5g SoluteThen add new solvent up to 95g final solution, so adding (95g - 10g =) 85 gram new solvent, then you'll get:9.5g Solute (in 10 g of original solution) in 95g (final) solution, thus 9.5g S / 95g = 10%m/mHowever if the meaning was: % by Volume ( %v/v) then calculation appears to get very complicated, but not impossible if you know at least the density values of all solutions (original 95%v/v and final 10%v/v) and of the solvent.(In that case mail me: JoppeDeQuint at answers dot com).DO NOT ever use: (orig. volume) + (added volume) = final volume.It's only a rule of thump, an approximation. This is because fluids can contract on mixing at dilution. There is no rule such as: conservation of volume.Your case: 10 ml + 85 ml (is not equal but) < 95 ml final solution.
What is the volume of 5g of gold?
To find the volume of 5 grams of gold, you can use the density of gold, which is approximately 19.32 grams per cubic centimeter (g/cm³). Volume is calculated using the formula: Volume = Mass / Density. Therefore, the volume of 5 grams of gold is about 0.259 cubic centimeters (cm³) when you divide 5 grams by the density of 19.32 g/cm³.
What is the volume of a 100 pound brick of gold?
To find the volume of a 100-pound brick of gold, we first need to know the density of gold, which is approximately 19.32 grams per cubic centimeter. Since 1 pound is about 453.592 grams, a 100-pound brick weighs approximately 45,359.2 grams. Using the formula for volume (volume = mass/density), the volume of the gold brick is about 2,347.7 cubic centimeters.
What is the volume of all the gold in the world?
seventy cubic feet
What is the mass of gold that has a volume of 10 and density of 19.3?
It is impossible to answer the question since there are no units given. Volume of 10 what? The density of gold is 19.3 gcm-3 which may imply that the volume is given in SI units, but that could be cubic metres, cubic centimetres or cubic micrometres.
