Hydrogen gas has a density of 0.090 g/L, and at normal pressure and -1.72 C one mole of it takes up 22.4 L. How would you calcul

BlackZzzverrR [31]

Answer:

$n= \frac{m}{ \rho }* \frac{1 mol}{22.4 L}$

Explanation:

Assuming that all caculations are at normal pressure and -1.72°C :

$n= \frac{m}{ \rho }* \frac{1 mol}{22.4 L}$

Where

$n$ is the number of moles of hydrogen

$n$ is the mass of hydrogen

$\rho$ is the density of hydrogen

If 112 g fr combines with 48 g of O2 how much fe2O3 is formed

maks197457 [2]

Answer:

160 g.

Explanation:

The balanced equation is

4Fe + 3O2 ---> 2Fe2O3.

4 * 56 g of Fe reacts with 6 * 16 g of O2 to give 2 * 160 g Fe2O3.

224 g Fe reacts with 96g of O2 to give 320 g Fe2O3.

So 48 g O2 + 224 g Fe produces 320 * 1/2 = 160 g Fe2O3.
