Explanation:
This will get you 3.6%
Answer:
3.98g
Explanation:
Given parameters:
Number of molecules = 1.2 x 10²⁴ molecules
Unknown:
Mass of H₂ = ?
Solution:
To find the mass of this molecule, we use the expression below:
Mass = number of moles x molar mass
Molar mass of H₂ = 2(1) = 2g/mol
6.02 x 10²³ molecules are contained in 1 mole of a substance
So; 1.2 x 10²⁴ molecules will have = 1.99 moles of H₂
Mass of H₂ = 1.99 x 2 = 3.98g
Answer:
Deposition
Explanation:
Deposition is the process of sediment being placed in a new location.
Triethanolamine has a formula of C6H15NO3. It is a polar molecule since the structure is unbalanced one side which makes it able to interact with water molecules. The central atom is N for this molecule. Hope this answers the question.
