Answer:
<h2>6.48 </h2>
Explanation:
The pH of a solution can be found by using the formula
![pH = - log ([ {H}^{+} ])](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%28%5B%20%7BH%7D%5E%7B%2B%7D%20%5D%29)
From the question we have
We have the final answer as
<h3>6.48 </h3>
Hope this helps you
<span>This question cannot be answered in actual centimeters unless at least one edge has a known length however it can be written as (length^3) or (length cubed). As an example if the sample of gold cube had one length of 3cm then all lengths would be 3cm on the cube.</span>
a) (NH4)2SO4 --- 1 mole of it contains 2 moles of N, 8 moles of H, 1 mole of S, and 4 moles of O.
MM = (2 moles N x 14.0 g/mole) + (8 moles H x 1.01 g/mole) + (1 mole S x 32.1 g/mole) + (4 moles O x 16.0 g/mole) = 132 g/mole.
6.60 g (NH4)2SO4 x (1 mole (NH4)2SO4 / 132 g (NH4)2SO4) = 0.0500 moles (NH4)2SO4
b) The molar mass for Ca(OH)2 = 74.0 g/mole, calculated like (NH4)2SO4 above.
4.5 kg Ca(OH)2 x (1000 g / 1 kg) x (1 mole Ca(OH)2 / 74.0 g Ca(OH)2) = 60.8 moles Ca(OH)2
The question is confusing and all the answers are not there but it is B C and D
