A student successfully neutralizes 25.0mL of HCl(aq) during a titration experiment with 18.5mL of 0.150M NaOH(aq). What is the c
son4ous [18]

Answer:

The concentration is 0.111 M.

Explanation:

Use dimensional analysis to solve the problem. Since both HCl and NaOH are strong, the dissociate completely in solution.

For this neutralization, the reaction is HCl + NaOH = NaCl + HOH

18.5 mL x \frac{1 L}{1000 mL} x \frac{0.150 moles NaOH}{1 L} x \frac{1 mole HCl}{1 mole NaOH} = 0.002775 moles HCl

Molarity = moles/ Liters

Molarity of HCl = 0.002775 moles HCl / 0.025 L = 0.111 M

Name three stars that are hotter than the sun
devlian [24]

Eta Carinae could be as large as 180 times the radius of the Sun, and its surface temperature is 36,000-40,000 Kelvin. Just for comparison, 40,000 Kelvin is about 72,000 degrees F. So it's the blue hypergiants, like Eta Carinae, which are probably the hottest stars in the Universe.
