Here, Equation: 2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O

We know, Concentration (c) = Number of moles(n) / Volume (v)

Substitute the given values, 
0.02 = n / 0.3   [ 300 mL = 0.3 L ]
n = 0.3 * 0.02
n = 0.006

Now, According to stoichiometry, There is 1 Molecule of Sodium sulfate produces for every 2 molecules of NaOH.

So, Number of Moles of Na₂SO₄ = 0.006/2 = 0.003

Given mass = Molar mass * Number of moles
M = 142.04 * 0.003
M = 0.426 g

In short, Your Answer would be: 0.426 g

Hope this helps!

Find the number of molecules in .815 mole of O2​
Simora [160]

Answer:

4.9 × 10²³ molecules

Explanation:

Given data:

Number of molecules = ?

Number of moles of oxygen = 0.815 mol

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ molecules

0.815 mol  ×  6.022 × 10²³ molecules  / 1 mol

4.9 × 10²³ molecules

What is the [h3o ] for a solution of seawater at 25°c that has a ph of 8.3?
Kipish [7]
PH of solution at 25ºC = 8.3

[ H_3O^+] = 10 ^{-pH}

{H_3O^+] = 10 ^{-8.3}

[H_3O^+] = 5.011*10^{-9}  M

hope this helps!
