1 answer:

7 0

As in relative abundance , one is take reference
So,
One is taken as 1:
Other is subtracted from it:
(1 - 0.6011)(atomic mass of Ga-71)

Equation can be written as:
69.723 = (0.6011)(68.9256) + (1-0.6011)x 
(1-0.6011) is the percentage abundance of Ga-71 expressed in percentage: 

Solving for x 
28.2918 = 0.3989 x 
x= 70.9246.......

If a solution has a pOH of 8.71, what is the [H+]?

TEA [102]

Answer: $5.1\times 10^{-6}M$

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

$pH=-\log [H^+]$

$pH+pOH=14$

Putting in the values:

$pH=14-8.71=5.29$

$5.29=-log[H^+]$

$[H^+]=5.1\times 10^{-6}$

Thus $[H^+]$ is $5.1\times 10^{-6}M$
