Web9 mei 2024 · where Π is the osmotic pressure in atm, i = van 't Hoff factor of the solute, M = molar concentration in mol/L, R = universal gas constant = 0.08206 L·atm/mol·K, and T = absolute temperature in Kelvin. Step 1: Determine the van 't Hoff factor. Since glucose does not dissociate into ions in solution, the van 't Hoff factor = 1. Step 2: Find the absolute … Web8 nov. 2024 · Because the concentration is a percent, you know a 100-gram sample would contain 12 grams of iron. You can set this up as an equation and solve for the unknown "x": 12 g iron / 100 g sample = x g iron / 250 g sample Cross-multiply and divide: x= (12 x 250) / 100 = 30 grams of iron How to Calculate Volume Percent Concentration of a Solution great escape ithaca mall

If would be = (6.02 x 10^23)x12 = 7.224x10^24. One molecule of glucose is C6H12O6. That means there is 6 carbon atoms, 12 hydrogen, and 6 oxygen, for 24 total atoms. If there are 12 molecules, 12 x 24 = 288 atoms all together.
