<span>Rust forms when 2 atoms of fe reacts with oxygen to form iron oxide as follows. 4Fe2 + 302 ==[]::::::::::::::::> 2Fe2O3. So basically 4 atoms of oxygen reacts with 3 atoms of oxygen to produce the product. We need to find the number of moles of Fe that reacts with Oxygen. Number of moles is the concentration of iron multiplied by the molarity. So we have 55 * 0.035 = 1.925 moles. Hence 1.925*4 atoms of iron which gives 7.7 moles will actually react with 3 *1.925 = 5.775 of Oxygen Since we know the number of moles of oxygen we can solve for its mass. No of moles = mass/molar mass. Mass = no of moles * molar mass = 5.775 * 32 = 184.5</span>

What is the mass of sulfuric acid in 50.0 mL of a 6.00 M solution?
Evgesh-ka [11]

Answer:

The answer to your question is 29.4 grams of H₂SO₄

Explanation:

Data

mass of sulfuric acid

volume = 50 ml

Molarity = 6 M

Process

1.- Write the formula of Molarity

Molarity = moles / volume

-Solve for moles

moles = Molarity x volume

-Substitution

moles = 6 x 0.05

-result

moles = 0.3

2.- Calculate the molar mass of Sulfuric acid

H₂SO₄ = (1 x 2) + (32 x 1) + (16 x 4) = 2 + 32 + 64 = 98 g

3.- Calculate the mass in the solution

                 98 g of H₂SO₄ ---------------- 1 mol

                    x                   ----------------- 0.3 moles

                            x = (0.3 x 98) / 1

                            x = 29.4 grams of H₂SO₄
