How many penicillin molecules would you have if you had a total of 36 hydrogen atoms? What would be the total atomic mass?
1 answer:
Answer:
Explanation:
Molecular formula of penicillin = C₁₆ H₁₈ N₂ O₄S
No of hygrogen atoms = 36
No of molecules = 36 / 18 = 2
molecular weight = 334 amu
molecular weight of 2 molecules = 334 x 2 = 668 amu.

Answer:
0.726 mol·L⁻¹
Step-by-step explanation:
c = moles/litres
=====
Moles = 29.8 × 1/342.30
Moles = 0.087 06 mol
=====
Litres = 120 × 1/1000
Litres = 0.120 L
=====
c = 0.087 06/0.120
c = 0.725 mol·L⁻¹
Answer:
The correct answer is A.
Answer:
Catod: K^(+), H2O
2H2O + 2e^(-) ---> H2 + 2OH^(-) reduction reaction
Anod: I^(-), H2O
2I^(-) ---> I2 + 2e^(-) oxidation reduction
2H2O + 2I^(-) ---> I2 + H2 +2OH^(-) ionic net reaction
