We need to know the statements lol
Molarity is number of moles of solute per one liter of solution. The symbol for molarity is a capital M. The molarity of the given solution will be 3.125M
A solution is a mixture of two or more substances in which neither of substance changes chemically. For example, the salt water is a solution that contains the water (the solvent) and salt (the solute). Concentration is amount of dissolved substance in a solution. In other words, it is amount of stuff that has been mixed into the liquid. Concentration is usually measured in the molarity.
Given that,
Number of moles= 1
Volume = 320ml= 0.320 L
Molarity= No of moles of solute/ Volume of solution in L
= 1/ 0.320
= 3.125 M

The volume of O₂ : 21 L
<h3>Further explanation</h3>
Given
8.7 grams of C₂H₄
Required
Volume O₂
Solution
Reaction
C₂H₄ + 3 O₂ ⇒ 2 CO₂ + 2 H₂O
mol C₂H₄(MW= 28 g/mol) :
= mass : MW
= 8.7 g : 28 g/mol
= 0.311
From the equation, mol O₂ :
= 3/1 x mol C₂H₄
= 3/1 x 0.311
= 0.933
At STP, 1 mol gas=22.4 L, so for 0.933 mol :
= 0.933 x 22.4 L
= 20.899 L ≈ 21 L
Answer:
H2SO4
Explanation:
Physical properties: H2SO4 is a colorless or slightly yellow viscous liquid with a pungent odor. It has a density of 1.84 g/mL, boiling point of 337 °C, and melting point of 10 °C. "Concentrated" sulfuric acid is 98% in water, and is the most stable form.
The answer is B. It has 8 protons
