A theory fits all three of these descriptions. you can test, predict, and prove or disprove a theory. hope this helps!
Answer:
0.570 L
Explanation:
Given:
Concentration of the HCl solution = 0.750 M
Mass of NaCl in the reaction = 25.0
Number of moles of NaCl in the reaction = Mass of NaCl / Molar mass of NaCl
also,
Molar mass of NaCl = 22.98 + 35.45 = 58.43 grams
thus,
Number of moles of NaCl in the reaction = 25 / 58.43 = 0.4278 moles
now,
1 mol of NaCl reacts to form 1 mol of HCl
thus,
0.4278 moles of NaCl reacts to form 0.4278 mol of HCl
also,
Concentration = Moles / volume of solution
0.750 = 0.4278 / volume of solution
or
volume of solution = 0.570 L
