Explanation:
Answer:
0.056 M
Explanation:
To calculate the concentration of h we must use the following formula:
10^-pH
So lets plug in our pH:
10⁻¹.²⁵
When we plug this into our calculator our answer is
0.056 M
Answer: 4 x 10 ∧-2 moles of nitrogen.
Explanation:
The chemical formular for quinine is ; C20 H24 N2 O2
As can be seen from the chemical formular;
1 mole of quinine contains 2 moles of Nitrogen
Thus; 2.0 x 10 ∧-2 moles of quinine would contain
2.0 x 10 ∧-2 x 2 = 4 x 10 ∧-2 moles of nitrogen.
Therefore 4 x 10 ∧-2 moles of nitrogen are in 2.0×10−2mole of quinine
