The molarity of the hydrochloric acid, HCl solution given the data is 0.079 M
<h3>Balanced equation </h3>
HCl + NaOH —> NaCl + H₂O
From the balanced equation above,
- The mole ratio of the acid, HCl (nA) = 1
- The mole ratio of the base, NaOH (nB) = 1
<h3>How to determine the molarity of HCl </h3>
- Molarity of base, NaOH (Mb) = 0.137 M
- Volume of base, NaOH (Vb) = 16.1 mL
- Volume of acid, HCl (Va) = 27.9 mL
- Molarity of acid, HCl (Ma) =?
MaVa / MbVb = nA / nB
(Ma × 27.9) / (0.137 × 16.1) = 1
(Ma × 27.9) / 2.2057 = 1
Cross multiply
Ma × 27.9 = 2.2057
Divide both side by 27.9
Ma = 2.2057 / 27.9
Ma = 0.079 M
Thus, the molarity of the HCl solution is 0.079 M

Aphelion in miles =94290301
Perihelion in miles = 91200281
Explanation:
To convert km in mile we use the multiply the distance in km with 0.62, because there are 0.62 miles in 1 km.
Aphelion in miles = aphelion in km × 0.62
Aphelion in miles = 152081132 × 0.62
Aphelion in miles =94290301
Perihelion in miles = perihelion in km × 0.62
Perihelion in miles = 147097229 × 0.62
Perihelion in miles = 91200281
