PH scale is used to determine how acidic or basic a solution is.
pH can be calculated as follows;
by knowing the ph we can calculate pOH
pH + pOH = 14
pOH = 14 - 8.1
pOH = 5.9
pOH is used to calculate the hydroxide ion concentration
pOH = -log[OH⁻]
[OH⁻] = antilog(-pOH)
[OH⁻] = 1.26 x 10⁻⁶ M
therefore hydroxide ion concentration is 1.26 x 10⁻⁶ M
Answer:
K8S4O16 or K8(SO4)4 depending on if the SO4 is supposed to represent sulfate or not
Explanation:
Find the molar mass of K2SO4 first:
2K + S + 4O ≈ 174 g/mol
Divide the goal molar mass of 696 by the molar mass of the empirical formula:
696 / 174 = 4
This means you need to multiply everything in the empirical formula by 4:
K2SO4 --> K8S4O16 or K8(SO4)4 depending on if the SO4 is for sulfate or not
Answer:2,204 pounds Ibuprofen must the factory use to fill this order
Explanation:
Amount of Ibuprofen in 1 tablet = 200 mg
Amount of Ibuprofen in 5,000,000 tablet = 
1 g = 1000 mg
Grams of Ibuprofen = 
1 g = 0.002204 pounds
Pounds of Ibuprofen required to fulfill the order:
2,204 pounds Ibuprofen must the factory use to fill this order
