Question- 1) 45.0 mL of 1.75 M NaOH is neutralized by 73.6 mL of an HCl solution. What is the molarity of the HCl solution.
2) A sample of Helium gas occupies 1,045 mL at 621 mmHg. For a gas sample at a constant temperature, determine volume of helium at 745 mmHg.
3) A gas temperature of 185 degrees C occupies a volume of 475 mL. Assuming constant pressure, determine the volume at 55 degrees C.
4) Calculate the volume, in liters of 4.75 mol H2S(g) at 90 degrees C and 1.75 atm.
5) If one strand of a DNA double helix has the sequence ATTCGGCTAC, what is the sequence of the other DNA strand?
Provide complete steps to solve the above question any help is appreciated
