Answer:
1.37x10²⁵atoms of carbon
2.74x10²⁵ atoms of oxygen.
33.7g of KNO₃
Explanation:
To answer this question you must use molar mass of carbon dioxide (44g/mol) and 1 mole are 6.022x10²³atoms.
1.00kg are 1000g of CO₂. Moles are:
1000g CO₂ * (1mol / 44g) = 22.73 moles of CO₂ = 22.73 moles of carbon.
In atoms:
22.73 moles C * (6.022x10²³atoms / 1mole) = 1.37x10²⁵atoms of carbon
There are 22.73 moles of CO₂ * 2 = 45.45 moles of oxygen are present in the carbon dioxide. In atoms:
45.45 moles Oxygen * (6.022x10²³atoms / 1mole) = 2.74x10²⁵ atoms of oxygen.
1 mole of Potassium nitrate, KNO₃, contains 3 moles of oxygen. 1 mol of oxygen are:
1.00 mol O * (1mol KNO₃ / 3 moles O) = 0.33 moles of KNO₃
As molar mass of KNO₃ is 101.1g/mol:
0.33 moles of KNO₃ * (101.1g / mol) = 33.7g of KNO₃
The rapid motion and collisions of molecules with the walls of the container causes pressure.
There are 32 :) hope is helps
KE=6,250Joules
You plug in your given numbers and remember to square 5 because that’s the speed
1. It is something we don't have to worry about ever losing.
2. We can use quite a bit of it.
3. Renewable energy saves us from wasting non reusable energy
4. We have something to use when we run out of non reusable energy
5. The energy is is helpful with everyday things.
