Total molecular mass of NaCl = atomic mass of sodium + atomic mass of chlorine. How many millilieters of a 12% (v/v) propyl alcohol solution would you need to obtain 5.7 mL of propyl alcohol? An important role to many important applications is structure and dynamics of water. WILL SCL2 and SCl4 have the same shape as CH4? NOTE In any two-component system, if the percent of one component is known, the other is automatically defined by difference; that is, if Na is 39.43 %, then Cl is What are some reasons your percent recovered is less than 100% or more than 100%? What are the names of God in various Kenyan tribes? What do you divide the mass of to calculate the percent concentration of a solution?
