If the formula of Borax is $\mathrm{Na_2B_4O_x(OH)_y~.~zH_2O}$, then $x+y+z=$ ___________
Answer (integer)
17
Solution
Borax, also known as sodium borate, has the chemical formula $\mathrm{Na_2B_4O_5(OH)_4~.~8H_2O}$.<br/><br/> Comparing this to the given formula, we can assign the values for x, y, and z:
<br/><br/>
x = 5 (from O₅)<br/><br/>
y = 4 (from (OH)₄)<br/><br/>
z = 8 (from 8H₂O)
<br/><br/>
Now, let's sum up the values of x, y, and z:
<br/><br/>
$x+y+z=5+4+8=17$
<br/><br/>
So, the value of $x+y+z$ is indeed 17.
