HELP ASAP I WILL GIVE BRAINLIST
Irina-Kira [14]

Answer:

10.7

Explanation:

According to this question, we have 4.60 × 10^-4 M hydroxide ion (OH-) concentration.

Since we were given the OH concentration, we first calculate the pOH of the solution, which is given as:

pOH = -log {OH-}

pOH = - log {4.60 × 10^-4}

pOH = - log {0.000460}

pOH = 3.337

pOH = 3.34

Given that; pOH + pH = 14

The pH of the solution = 14 - pOH

pH = 14 - 3.34

pH = 10.66

pH = 10.7

babunello [35]

Answer:

1/2 , no difference to the fraction of the sons

Explanation:

Since the disorder is inherited recessive gene on the X. The woman will be a carrier since her father had G6PD. Therefore her genotype is X Xh

The normal man genotype will be XY

The genotype of their offspring will be

  • Daughters XX, XXh
  • Sons   XY, XhY

Therefore 1 out of the 2 sons(1/2) will have the disorder

If the father had the disorder, it will not change the fraction of the sons  because the disorder is on the X chromosome. However one of the daughters will have it XhXh
