The average atomic mass in amu of element X is 58.42 amu
The average atomic mass is the sum of the mass number of each of the isotopes multiplied by their respective abundances.
So;
The average atomic mass of element X is;
(58 * 0.68) + (60 * 0.26) + (0.06 * 62)
= 39.44 + 15.26 + 3.72
= 58.42 amu
The average atomic mass in amu of X is 58.42 amu.

To answer this question, you need to know the equation for the reaction. The equation should look like this:
<span>2K3PO4 (aq) + 3NiCl2 (aq) --> Ni3(PO4)2 (s) + 6KCl (aq)
</span>
In the equation, 2 K3PO4 would react with 3 NiCl2. Then the calculation should be look like this:
V2= V1*m1/m2 *2/3
V2= 134ml * <span>0.0112/</span>0.225 *2/3
V2= 4.46ml
Answer: 22 grams because mass cannot be created or destroyed
Explanation: I just took the test
A and d because a chain reaction can be really rare at times
