If 80.0 grams of oxygen gas is consumed with a stoichiometric equivalent of aluminum metal, how many grams of aluminum oxide (mo
Pachacha [2.7K]

Answer:

170 g

Explanation:

Moles of Oxygen gas :

Given, Mass of Oxygen = 80.0 g

Molar mass of Oxygen gas= 31.998 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{80.0\ g}{31.998\ g/mol}

Moles\ of\ O_2=2.5\ mol

The reaction between Al and O₂ is shown below as:

4Al + 3O₂ ⇒ 2Al₂O₃

From the reaction,

3 moles of O₂ on reaction forms 2 moles of Al₂O₃

1 mole of O₂ on reaction forms 2/3 moles of Al₂O₃

2.5 moles of O₂ on reaction forms (2/3)*2.5 moles of Al₂O₃

Moles of Al₂O₃ = 1.6667 moles

Molar mass of Al₂O₃ = 102 g/mol

Mass = Moles * Molar mass = 1.6667 * 102 g = 170 g

Osmosis involves a semi-permeable membrane with small pores that allow the solvent to travel across the membrane; however, large
lesya692 [45]

Answer: solvent will move from the first compartment containing 3% glucose into the second compartment containing 6% glucose.

Explanation: osmosis is defined as the movement of solvent (example water molecules) from a region of lower concentrated solution into the region of more concentrated solution. The first compartment contains less glucose concentration with more solvent. Therefore, solvent will move from the first compartment with less glucose concentration into the second compartment containing 6% glucose concentration to achieve an equalised concentration of solute on both sides of the semi permeable membrane.
