How do you find solubility? I am given only the temperature and the substance is KNO3. I don’t need anyone to solve it for me, j
skad [1K]
There’s no formula that relates solubility to temperature, but you can look up the solubility constant Ksp of substance given and then take the square root of that to find solubility.

Fe2O3(s)+3C(s)→2Fe(s)+3CO(g) how many grams of CO are produced when 32.0 grams of C react
krok68 [10]

Answer:

74.6 g

Explanation:

The computation of the number of grams produced at the time when 32.0 grams of C react is shown below:

As we know that

But before that we need to find out the moles of c i.e carbon which is

= \frac{Grams }{C\ molar\ mass}

= \frac{32\ grams}{12.0107 g/mol}

= 2.66 mol

As we know that

1 mol of C produces 1 mol of CO

So, for 2.66 mol, the mass of CO is

= 2.66 \times28.0101 g/mol

= 74.6 g

Basically we applied the above equation so that we can reach to the answer
