<h3>Further explanation</h3>
Given
5 g of gold
0.1% gold by mass
Required
Pounds of gold ore
Solution
For percent mass = 0.1%, than mass of gold ore :
Conversion factor :
1 g = 0,00220462 pound, than for 5000 g = 11,02311 pounds
Generally there are two kinds of bleaching agents, notably chlorine (and many chlorine compounds such as sodium hypochlorite) and peroxygen bleaching agents (such as hydrogen peroxide). This isn't to say there aren't others, because there are, such as ammonia. (Note, mixing traditional bleaches and ammonia is very dangerous)
Volume of the solution =
= 2 L solution x
Volume of solute = 7.5 mL
Volume of water (solvent) = 2000 mL - 7.5 mL = 1992.5 mL water
Star clusters is the only thing i can think of that would apply.
