You are watching: How many moles of silicon (si) atoms are equivalent to 65.8 g si?


2 is the price buuu 2.34 mol is the exactly answer. The molar massive of Silicon is 28.0855 grams division 65.8g by that number to obtain 2.34

2.35 moles of Silicon space equivalent.

Explanation: Moles have the right to be calculated as:

*

Here, Si atom is given, therefore substituting the masses in over equation, us get

Molar mass = 28 g/mol

Given massive = 65.8 g

*

Moles the Si atoms = 2.35 moles


*

7. Using your expertise of colligative properties explain whether sodium chloride or calcium chloride would be a much more effective problem to melt the ice on a slick sidewalk. Usage 3 – 4 sentences in your explanation. 8. As soon as a 2.5 mol of street (c12h22o11) are included to a specific amount that water the boiling allude is increased by 1 celsius degree. If 2.5 mol that aluminum nitrate is included to the very same amount that water, by just how much will certainly the boiling point be changed? present all calculations leading to your answer or use 3 – 4 sentence to define your answer. 9. If 5.40 kcal of warm is included to 1.00 kg of water at 100⁰c, just how much vapor at 100⁰c is produced? present all calculations leading to an answer. 10. The freezing of water at 0⁰c can be represented as follows: h2o (l) ↔ h2o(s) the thickness of liquid water is 1.00 g/cm3. The thickness of ice is 0.92 g/cm3. In 3 – 4 sentences describe why using pressure causes ice to melt.

The human eye consists of a molecule called 11-cis-retinal that changes shape when struck through light of adequate energy. The readjust in form triggers a collection of events that results in an electrical signal being sent to the brain that results in vision. The minimum energy required to adjust the conformation of 11-cis-retinal in ~ the eye is about 164 kj/mol.
