Using chemical equation to find moles of product from moles of reactant
Zolol [24]

Answer:

0.21 mole of C8H18.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

2C8H18 + 25O2 —> 16CO2 + 18H2O

Next, we shall determine the number of mole of C8H18 that reacted and the number of mole water (H2O) produced from the balanced equation.

This is illustrated below:

From the balanced equation above,

2 moles of C8H18 reacted to produce 18 moles of H2O.

Finally, we shall determine the number of mole C8H18 needed to produce 1.90 moles of H2O.

This can be obtained as follow:

From the balanced equation above,

2 moles of C8H18 reacted to produce 18 moles of H2O.

Therefore, Xmol of C8H18 will react to produce 1.90 moles of H2O i.e

Xmol of C8H18 = (2 × 1.90)/18

Xmol of C8H18 = 0.21 mole

Thus, 0.21 mole of C8H18 is needed for the reaction.

192 grams of (NH 4 ) 2 CO 3 (N Molar Mass : 96g ) are dissolved to make 2150 mL of solution , what is the concentration of this
svlad2 [7]

The concentration of a solution of 192 grams dissolved to make 2150 mL of solution is 0.93M. Details about concentration can be found below.

<h3>How to calculate concentration?</h3>

The concentration of a solution can be calculated by dividing the number of moles of the substance by its volume.

no of moles of NH42CO3 = 192g ÷ 96g/mol = 2 mol

Concentration of solution = 2 moles ÷ 2.15L

Concentration of solution = 0.93M

Therefore, the concentration of a solution of 192 grams dissolved to make 2150 mL of solution is 0.93M.
