Answer:
<h3>The answer is 2 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question we have
We have the final answer as
<h3>2 g/cm³</h3>
Hope this helps you
CO2: 12.0107 + 15.9994(2) = 44
NH3: 14.0067 + 1 (3) = 17
1.55 (17/44) = .599g
Answer: Multiply the mass by the inverse of molar mass, and then multiply by Avogadro's number.
Explanation: Convert the mass to moles, multiply the number of moles by the ratio of the number of atoms or ions to one mole, multiply by Avogadro's number.
Answer:
ΔH vaporization of chloroform is 30.1kJ/mol
Explanation:
It is possible to find ΔH of vaporization of certain compound knowing vapor pressure under 2 different absolute temperatures (In Kelvin) by using Clausius-Clapeyron equation:
<em>Where P is vapor pressure. R is gas constant (8.314J/molK) and T absolute temperature of 1, first state and 2, final state.</em>
Absolute temperatures in the problem are:
T₁ = 24.1°C + 273.15 = 297.25K
T₂ = -6.3°C + 273.15 = 266.85K
Replacing:
30073J/mol = 30.1kJ/mol = ΔHVap
<h3>ΔH vaporization of chloroform is 30.1kJ/mol</h3>
