Answer:
The prefixes tell you how many of each there are.
Explanation:
So for this example, mono would mean there is one sugar, di meaning 2 sugars and so on. Hope this helped!
Here is a table:
mono- 1 hexa-6
di-2 hepta- 7
tri- 3 octo- 8
tetra- 4 nona- 9
penta - 5 deca- 10
<u>Answer:</u> The molarity of
ions in the solution is 0.306 M
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:

We are given:
Mass of solute
= 15.6 g
Molar mass of
= 295.6 g/mol
Volume of solution = 345 mL
Putting values in above equation, we get:

As, 1 mole of
produces 1 mole of copper (II) ions and 2 moles of nitrate ions.
So, molarity of
ions = (2 × 0.153) = 0.306 M
Hence, the molarity of
ions in the solution is 0.306 M
89.1% Au
The molar mass of Au2O3 is 2(196.97) + 3(16.00) = 441.94 g/mol
The mass percent of Au is therefore 2(196.97) / 441.94, which is 393.94/441.94 = 0.891 —> 89.1%
