Compute the amount of 1.00x10-3 M phosphate stock solution must dilute to make 100.mL of 1.50x10 -5 M phosphate.
Explain where R is proportionality constant. The units of R are determined by the units of pressure as well as volume used in the equation. When atm is utilized for pressure and L for volume the appropriate R value is 0.0821 L⋅atm/mol⋅K.
