Hope this helps *smiles*
Sorry if it’s wrong
Data Given; T = 306 K
M.mass of CO = 28 g/mol = 0.028 Kg/mol
M.mass of CO₂ = 44 g/mol = 0.044 Kg/mol
M.mass of SO₃ = 80 g/mol = 0.080 Kg/mol
Gas Constant = R = 8.314 J/mol.K
Formula used; Vrms =
Putting values for CO; Vrms =
Vrms = 477 m.s⁻¹
Putting values for CO₂; Vrms =
Vrms = 380 m.s⁻¹
Putting values for SO₃; Vrms =
Vrms = 282 m.s⁻¹
Kinetic Energy;
K.E = 1/2 mv²
Putting values,
For CO,
K.E = 1/2 (0.028 Kg/mol) (477 m/s)²
K.E = 1/2 (0.028 Kg) (227529 m²/s²)
K.E = 3185 Kg.m².s⁻²For CO₂
,
K.E = 1/2 (0.044 Kg/mol) (380 m/s)²
K.E = 1/2 (0.044Kg) (144400 m²/s²)
K.E = 3176 Kg.m².s⁻²For SO₃
,
K.E = 1/2 (0.080 Kg/mol) (282 m/s)²
K.E = 1/2 (0.080 Kg) (79524 m²/s²)
K.E = 3180 Kg.m².s⁻²
Answer:
1.14kg of chalcopyrite
Explanation:
In 1 mole of chalcopyrite, CuFeS₂, there is 1 mole of Cu. Thus, to solve this question we need to convert the mass of pure Cu to moles using molar mass (Cu = 63.546g/mol). Then, the moles of Cu are equal to moles of chalcopyrite that must be converted to grams and then to kg (CuFeS₂: 183.54g/mol)
<em>Moles Cu:</em>
395g Cu * (1mol / 63.546g) = 6.216 moles Cu = 6.216 moles CuFeS₂
<em>Mass chalcopyirite:</em>
6.216 moles CuFeS₂ * (183.54g/mol) = 1140.9g
<em>In kilograms:</em>
1140.9g * (1kg / 1000g) =
<h3>1.14kg of chalcopyrite</h3>
