The ideal gas law is presented
by the equation PV = nRT. n, the number of moles, is equal to mass over molar
mass. And density is M/V.
PV = nRT
PV = (M/molar mass)RT
P/RT = (1/molar mass)(M/V)
M/V = D = (molar mass)(P/RT)
Molar mass of CO2 = 44 g/mol
D = (molar mass)(P/RT)
D = (44 g/mol)(1 atm)/(0.08206
L-atm/mol-K)(273K)
D = 1.964 g/L
Answer:
A. Electrolyte
Explanation:
Concentrated sulfuric acid has a density of 1.84 g/millimeter. When you dilute this with water to 5.20 M, you then have a density of 1.30 g/millimeter, which then can be used as a lead storage for batteries in automobiles. (Got help to answer this at Www.wyzant.com
Answer:
A sample that has low pH, will have a [OH⁻] < 1x10⁻⁷
Explanation:
Kw = 1x10⁻¹⁴
[H₃O⁺] = 1x10⁻⁷
[OH⁻] = 1x10⁻⁷
If pH is very low, [H₃O⁺] > 1x10⁻⁷
For example, [H₃O⁺] = 1x10⁻³ M
- log [H₃O⁺] = pH
- log 1x10⁻³ M = pH = 3
[OH⁻] will be < 1x10⁻⁷
For the example we made before
pH = 3
pOH = 14 - pH → 11
10^-pOH = [OH⁻]
10⁻¹¹ = 1x10⁻¹¹
Two substances that are evenly mixed together. I hope this helped:)
