6. Make 20 mL of a 0.3 M NaCl solution from a 0.6 M NaCl stock solution. 7. Make 170 mL of 60% ethanol from a 95% ethanol stock. 8. Make 420 ml of IX SSC from a 15X SSC stock. (Remember, it doesn't matter what the units are or what the chemicals are. The calculation is the same.) 9. Make 1 mL of 4 mM CaCl, from a IM stock. 10. Make one single 100 mL solution that is 100 mM KCI, 5.0 mM Pipes buffer, 4 mM EDTA, 4 mM MgCl, from 1 M stocks of each of these chemicals
