- The atomic mass of carbon is 12.011 g/mol.
- The atomic mass of hydrogen is 1.00794 g/mol.
This means the molar mass of CH is

Dividing the given molar mass by this,
This means the molecular formula is 
Answer: A:5 B:2 C:15 D:8 E:O
Explanation:
just checked on edg
The answer should be B - Nitrogen Dioxide.
Answer: when concentrations of acid and base are same, pH = pKa
PH = 12.38 pOH = 1.62
Explanation: pKa= -log(Ka)= 12.38. PH + pOH = 14.00
Answer: Cornea
Explanation: The cornea is the only part of a human body that has no blood supply as it gets oxygen directly through the air.
