1 mol of any substance is made of 6.022 x 10²³ units, these units could be atoms making up elements or molecules making up a compound.
In this case. 1 mol of Li is made of 6.022 x 10²³ atoms of Li
The molar mass of Li is 6.94 g/mol
Therefore mass of 1 mol of Li is 6.94 g
In 6.94 g of Li there are - 6.022 x 10²³ atoms
Then in 766.3 g of Li there are - 6.022 x 10²³ atoms / 6.94 g x 766.3 g = 665 x 10²³
There are 6.65 x 10^25 atoms of Li
Answer:
Increase the concentration of the solution
Explanation:
Increasing the solute would increase the concentration. Increasing the solvent would decrease the concentration. For instance, if your lemonade was too tart, you would add more water to decrease the concentration
Answer:
165 g
Explanation:
Law of Conservation of Matter states that neither matter or energy is destroyed but instead transferred.
Since we need a total of 180 g, we need to subtract 15g of one of the products to find the missing amount:
180 g - 15 g = 165 g Cu produced
Answer:
less, decreases
Explanation:
When the pressure of an atmosphere occurs because of the force exerted so at the time of the higher altitudes, the air mass i.e. above the earth should be less as the air is attracted towards surface of an earth because of the gravity and air contains the mass that shows near the surface area so automatically the air density reduced due to which the mass also decreased
Answer: 4.04 ounce
Explanation: Given: Peanut butter contained in the jar = 1.43 kg
Used Peanut butter=8.0 % of 1.43kg = 
As we know
