Answer:
Explanation:
<u>Given Data:</u>
Mole = n = 0.1 mol
Pressure = P = 530 mmHg = 0.7 atm
Volume = v = 8 L
Ideal gas constant = R = 0.8206 L atm K⁻¹ mol⁻¹
<u>Required:</u>
Temperature = T = ?
<u>Formula:</u>
Pv = nRT
<u>Solution:</u>
Rearranging for T
![\displaystyle T = \frac{Pv}{nR} \\\\T = \frac{(0.7)(8)}{(0.1)(0.08206)} \\\\T = \frac{5.6}{0.008206} \\\\T = 682.4 \ K\\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20T%20%3D%20%5Cfrac%7BPv%7D%7BnR%7D%20%5C%5C%5C%5CT%20%3D%20%5Cfrac%7B%280.7%29%288%29%7D%7B%280.1%29%280.08206%29%7D%20%5C%5C%5C%5CT%20%3D%20%5Cfrac%7B5.6%7D%7B0.008206%7D%20%5C%5C%5C%5CT%20%3D%20682.4%20%5C%20K%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)
Answer:
What is the mass of solute, in grams, in 250.00 mL of a 0.0125 M solution of KMnO4? Moles KMnO4 = M × V = 0.0125 M × 0.250 L = 3.13 × 10-3 mol KMnO4 grams KMnO4 = 3.13 × 10-3 mol KMnO4 × ( 158.03 g KMnO4/1 mol KMnO4) = 0.495 g 4.
Answer:
The wavelength of radio wave is 3m
Explanation:
speed of r.w (v) = 3 × 10⁸ m/s
frequency (f) = 1 × 10⁸ Hz
wavelength (λ) = ?
λ = v/f
= (3 × 10⁸) ÷ (1 × 10⁸)
= 3m
(Correct me if i am wrong)
Hydrogen peroxide is another way of dihydrogen dioxide
So,
H2 + O2 = H2O2 or 1 hydrogen per 1 oxygen
