Answer: 1.65
Explanation:
For a 0.0224M HCl solution the concentration of the hydrogen ions,
[H+] = is 0.0224 mol/L (i.e. 0.0224 M)
pH = −log[H+]
Substituting H+ = 0.0224 into the equation
pH = - log[0.0224]
pH = 1.649
pH = 1.65
Answer:
Estoy confundido.Puedes ser un poco especifico sobre tu pregunta?
Explanation:
C = 12
O2 = 16*2= 32
CO2 = (12)+(16*2) = 44
32/44*100 = 72.73%
The average the natural abundances of the various isotopes of carbon to arrive at the fractional mass.
