Answer:
220
Explanation:
V₀= Vmax(D)/ (D) + km
0.66/100=vmax(130km)/(130km)+(km)
Vmax= 0.66×131/130×1000 =0.6650mm/d
kwat= vmax/ET
=0.665×10⁻³/ 3×10⁻⁶
= 0.22×10³
= 220

Answer:
102.0 g/mol.
Explanation:
Aluminum oxide or Al2O3 is a chemical compound composed of 3 Oxygen and 2 aluminum atoms. Naturally, it is present in the form of mineral corundum in crystalline polymorphic forms. It holds significant importance in the preparation of Aluminium metal that is used as a refractory material.
To calculate the molar mass of Aluminum oxide, we will add the molar mass of 2 Al and 3 O atoms.
Since molar mass of Al is: 26.98 g
Molar mass of O is: 16.00 g
Molar mass of Al2O3
= (26.98)2 + (16.00) 3
= 53.96 + 48
= 101.96 g/mol
Since it is mentioned in question to round off the answer upto 4 significant figures, it will make the answer: 102.0 g/mol.
Hope it help!
<span>When you have a polar molecule, your bonds will not cancel out. This means that in a polar bond, the electronegativity of the atoms will attend to be different. For non-polar bonds the electro-negativity of the atoms will also be equal. In a polar bond you will have an unequal sharing of electron pairs which causes a molecular dipole. I hope this helps.
