Verizon [17]3 years ago
7 0

Answer:

Molarity = 2.0833 M (Approx)

Explanation:

Given:

Number of moles (n) = 0.25

Volume of solution = 120 ml = 0.12 L

Find:

Molarity

Computation:

Molarity = Number of moles (n) / Volume of solution.

Molarity = 0.25 / 0.12

Molarity = 2.0833 M (Approx)

Consider the following reaction. Zn(s) 2agno3(aq) --> 2ag(s) zn(no3)2(aq)when 16. 2 g of silver was produced, _____ mole(s) o
Crazy boy [7]

The required amount of silver nitrate to produce 16.2g of silver is 25.48 grams.

<h3>What is the relation between mass & moles?</h3>

Relation between the mass and moles of any substance will be represented as:

n = W/M, where

  • W = given mass
  • M = molar mass

Moles of silver = 16.2g / 107.8g/mol = 0.15mol

From the stoichiometry of the given reaction it is clear that, same moles of silver nitrate is required to produce same moles of silver. So 0.15 moles of silver nitrate is required.

Mass of silver nitrate = (0.15mol)(169.87g/mol) = 25.48g

Hence required mass of silver nitrate is 25.48g.

How do you balance this Chemical Equation? <br>C5H12O + O2 = CO2 + H2O​
ICE Princess25 [194]

Answer:

The chemical equation by putting, a 2 on C₅H₁₂O, 15 on O₂, 10 on CO₂ , and 12 on H₂O in the equation;

2C₅H₁₂O + 15O₂ → 10CO₂ + 12H₂O​

Explanation:

  • Chemical equations are balanced by putting coefficients on the reactants and products to ensure the total number of atoms on the left side equal to those on the right side.
  • Balancing chemical equations is done to make chemical equations obey the law of conservation of mass.
  • According to the law of conservation of mass, the mass of the reactants should always be equal to the mass of products.
  • This is done by balancing chemical equations to ensure the total number of atoms on the left side is equal to that on the right side.
  • Therefore, the balanced equation is;

          2C₅H₁₂O + 15O₂ → 10CO₂ + 12H₂O​
