9.98 g of NH₃ reacts with 23.4 g of O₂ (up to 3 significant figure).

<h3>What is Significant figures ?</h3>

The digits of a number that are used to express it to the required degree of accuracy, starting from the first non-zero digit.

The given chemical equation ;

4NH₃ + 5O₂ ---> 4NO + 6H₂O

Therefore,

4 moles of NH₃ reacts with 5 moles of O₂.

i.e,

68 g of NH₃ reacts with 160g of O₂.

Therefore,

9.98 g of NH₃ reacts with :

= 160/68 x 9.98

= 23.4 g of O₂ (up to 3 significant figure)

What is the molarity of a solution that contains 17g of NH₃ in 0.50L of solution?

erastovalidia [21]

Explanation:

Because molarity is mol/L, we'll have to convert 17g to mol.

After obtaining the mol, we'll divide that by the volume to obtain Molarity.

As the ph approaches 0, what happens to the concentration of h3o+ ions?

natta225 [31]

We know that

pH = -log[H+]

the pH value falls in between 0- 7 for acids

As the pH value increases the concentration of [H+] increases.

similarly as the value of pH approaches 0, the concentration of H+ increases

The solution said to become more acidic

Also

[H+] X [OH-] = 10^-14

Thus pH + pOH = 14

hence the concentration of OH- decreases as the pH approaches zero

What is the molarity of a solution prepared by dissolving 8 grams of BaCl2 in enough water to make a 450. 0 mL solution? (Hint:

Salsk061 [2.6K]

Molarity is the molar concentration of the solute dissolved in a volume of a solution. The molarity of the solution prepared by dissolving barium chloride will be 0.085 M.

<h3>What is molarity?</h3>

Molarity is the ratio of the moles of the solute to that of the volume of the solution in Liters. It can be given as,

$\rm Molarity = \dfrac{moles}{Volume}$

Here, moles of the barium chloride can be given by the mass and the molar mass and volume is given as 0.450 L.

Substituting values in the equation:

$\begin{aligned}\rm Molarity &= \rm \dfrac{mass}{Molar \;mass\times Volume}\\\\&= \dfrac{8}{208.23\times 0.450}\\\\&= 0.085\;\rm M\end{aligned}$

Therefore, 0.085 M barium chloride is the molar concentration.
