Answer: 121.95587 g/mol
Explanation:
- The atomic mass of aluminum is 26.98154 g/mol.
- The atomic mass of phosphorous is 30.97673 g/mol.
- The atomic mass of oxygen is 15.9994 g/mol.
Therefore, the molecular mass is:
The country located at coordinates N 35°00' 00", latitude and E 33°00' 00" longitude is Cyprus and is surrounded by the Mediterranean Sea. The country I would like to go to would be the one located at coordinates N 41°89'01" E 12°49'22".
<h3>What is a geographic coordinate?</h3>
Geographic coordinates is a term that refers to a reference system that has the objective of identifying a point located on Earth using a system of numbers, letters or symbols.
The geographical coordinates take as reference points the Greenwich meridian (longitude 0°) and the line of the equator (latitude 0°). On the other hand, longitudes range from 0° to -180° or 180° and latitudes range from 0° to 90° or -90°.
According to the above, it can be inferred that the location of the coordinates N 35°00' 00", latitude and E 33°00' 00" longitude is the country of Cyprus surrounded by the Mediterranean Sea.

Answer: number of atoms is 5.21 · 10^24
Explanation: Atomic mass of Be is 9.012 g/mol.
Number of moles n = m/M = 78.0 g / 9.012 g/mol =
Multiply this with Avogadro number Na = 6.022*10^23 1/mol
The heat energy from the fire is transferred to the pot by
- <em>radiation</em> — the hot coals radiate heat to the pot.
- <em>convection</em> — the hot gases from the fire travel upward until they reach the pot
The pot absorbs the heat energy and <em>conducts</em> the heat to the water inside.
The hot water <em>conducts</em> heat to the peas in three steps:
- warming the frozen ice and peas to 0 °C.
- thawing the ice and peas at 0 °C.
- heating the peas to 100 °C and cooking them at that temperature.
<em>Note</em>: Heat always flows spontaneously from a hotter to a cooler object.
