Write the group number and draw the electron-dot symbol for each of the following elements: a. sulfur b. nitrogen c. calcium d. sodium e. gallium
Step 1 of 3
Solutions Use of Van’t Hoff equation to find molecular weights of macromolecule cells o Know mass of the macromolecular sample o Dissolve the sample as ‘B’ in your osmotic pressure apparatus o Measure pi, T (temperature), and known R (gas constant) o Calculate molarity o Calculate molecular weight (measured in Daltons) Engineering application: o Apply excess pressure to the solute-containing side of the apparatus. This drives solvent from the solution to the pure solvent “reverse osmosis” Colloidal dispersions Phase Primary Secondary Type Example Gas Solvent Solute -------- --
