Answer:
38.7 g is the answer to your question. Your welcome:)
Answer:
unsaturated solution
Explanation:
Given: Epsom salts have a solubility 26.2 grams.
By definition,Solubility is the maximum amount of solute that can be dissolved in 100 g of water.
A solution is called saturated solution when the concentration of solute becomes equal to its solubility.
If the concentration of solute is less than solubility it is called unsaturated solution.
In this case: solubility is 26.2 grams.
If we dissolve 26 grams of Epsom salt in 100 g of water , concentration of solute is less than the solubility(26.2 g in 100 g of water) , hence it is an unsaturated solution.
I think the answer is electrons configuration
The empirical and molecular formula : C₂₁H₂₂N₂O₂

Given
The percent composition of an unknown substance is 75.42% Carbon, 6.63 % Hydrogen,
8.38 % Nitrogen, and 9.57 % Oxygen
Required
The empirical and molecular formula
Solution
C : 75.42 : 12 = 6.285
H : 6.63 : 1 = 6.63
N : 8.38 : 14 = 0.599
O : 9.57 : 16 = 0.598
Divide by 0.598
C : H : N : O = 10.5 : 11 : 1 : 1 = 21 : 22 : 2 : 2
The empirical formula : C₂₁H₂₂N₂O₂
(C₂₁H₂₂N₂O₂)n = 334
(334)n=334
n = 1
