50.0 mL of an HNo3 solution were titrated with 36.90 mL of a 0.100 M LiOH solution to reach the equivalence point. What is the m
sleet_krkn [62]
Answer: 0.0738 M

Explanation:


1) Chemical equation:

<span>HNO₃ + LiOH → LiNO₃ + H₂O
</span>

2) Mole ratios:

1 mol HNO₃ neutralizes 1 mol LiOH

3) Number of moles of H⁺ from HNO₃:

M = n / V ⇒ n = M × V = 0.050 liter × M

4) Number of moles of OH⁻ from LiOH

M = n / V ⇒ n = M × V = 0.03690 liter × 0,100 M

5) Equivalence point:

number of moles of H⁺ = number of moles of OH⁻

⇒ 0.0500 × M = 0.03690 × 0.100 

⇒ M = 0.03690 × 0.100 / 0.0500 = 0.0738 M

PV=mRT
coldgirl [10]

Answer:

The answer to your question is: P = 419933.5 Pa

Explanation:

Data

R = 0.287 KJ/Kg°K = 287 J/Kg°K

mass = 2 kg

T = 35 °C = 308°K

Container = 0.750 meters each side

Volume = l x l x l

             = 0.750 x 0.750 x 0.750

            = 0.421 m³

P = mRT / V

P = (2)(287)(308) / 0.421

P = 176792 / 0.421

P = 419933.5 Pa
