2 C2H6 + 7 O2 → 4 CO2 + 6 H2O

algol13

Answer:

x = 4.5

4.5 moles of C2H6 is required to produce 13.5 moles of H2O

Explanation:

Given equation is :

2 C2H6 + 7 O2 → 4 CO2 + 6 H2O

if it requires 2 moles of C2H6 to produce 6 moles of H2O

then x moles of C2H6 is required to produce 13.5 moles of H2O

Using unitary method for solving, we get

x = 13.5 x 2 / 6

x = 13.5 / 3

x = 4.5

Therefore, 4.5 moles of C2H6 is required to produce 13.5 moles of H2O

When 27.50 liters of oxygen gas reacts with excess hydrogen gas at STP how many grams of water is produced?

telo118 [61]

Answer: The mass of water produced is 44.28 g

Explanation:

We are given:

Volume of oxygen gas = 27.50 L

At STP conditions:

22.4 L of volume is occupied by 1 mole of a substance

27.50 L of oxygen gas will be occupied by = $\frac{1mol}{22.4L}\times 27.50L=1.23mol$

The chemical equation for the formation of water follows:

$2H_2+O_2\rightarrow 2H_2O$

By the stoichiometry of the reaction:

If 1 mole of oxygen gas produces 2 moles of water

So, 1.23 moles of oxygen gas will produce = $\frac{2}{1}\times 1.23=2.46mol$ of water

The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ ......(1)

Molar mass of water = 18 g/mol

Plugging values in equation 1:

$\text{Mass of water}=(2.46mol\times 18g/mol)=44.28g$

Hence, the mass of water produced is 44.28 g
