A 11.79 g sample of Mo2O3(s) is converted completely to another molybdenum oxide by adding oxygen. The new oxide has a mass of 1
Elis [28]

Answer:

MoO₃

Explanation:

To solve this question we must find the moles of molybdenum in Mo2O3. The moles of Mo remain constant in the new oxide. With the differences in masses we can find the mass of oxygen and its moles obtaining the empirical formula as follows:

<em>Moles Mo2O3 -Molar mass: 239,878g/mol-</em>

11.79g * (1mol / 239.878g) = 0.04915 moles Mo2O3 * (2mol Mo / 1mol Mo2O3) = 0.09830 moles Mo

<em>Mass Mo in the oxides:</em>

0.09830 moles Mo * (95.95g/mol) = 9.432g Mo

<em>Mass oxygen in the new oxide:</em>

14.151g - 9.432g = 4.719g oxygen

<em>Moles Oxygen:</em>

4.719g oxygen * (1mol/16g) = 0.2949 moles O

The ratio of moles of O/Mo:

0.2949molO / 0.09830mol Mo = 3

That means there are 3 moles of oxygen per mole of Molybdenum and the empirical formula is:

<h3>MoO₃</h3>

Why rock from earth cannot be used to determine earth age<br>​
Reptile [31]

Answer:So far scientists have not found a way to determine the exact age of the Earth directly from Earth rocks because Earth's oldest rocks have been recycled and destroyed by the process of plate tectonics. If there are any of Earth's primordial rocks left in their original state, they have not yet been found.
