A 6.0 mol sample of C3H8(g) and a 20. mol sample of Cl2(g) are placed in a previously evacuated vessel, where they react accordi

gladu [14]

2 CH₃CH₂CH₃ + 2 Cl₂ → CH₃CH(Cl)CH₃ + CH₃CH₂CH₂Cl + 2 HCl
so according to balanced equation we notice that:
2 mole of propane reacts with 2 moles of Cl₂, so 6 moles of propane will need to react completely with 6 moles Cl₂ (This mean Cl₂ present in excess and propane is the Limiting reagent)
2 mole C₃H₈ gives 2 moles HCl
6 moles C₃H₈ gives ? moles HCl
by cross multiplication we have 6 moles of HCl formed

How many moles of Fe are produced from 7 moles of Zn? Zn(s) + FeSO4(aq) → ZnSO4(aq) + Fe(s)

guajiro [1.7K]

Answer:

7 mol Fe

General Formulas and Concepts:

Chemistry

Stoichiometry

Explanation:

Step 1: Define

RxN: Zn (s) + FeSO₄ (aq) → ZnSO₄ (aq) + Fe (s)

Given: 7 moles Zn

Step 2: Stoichiometry

$7 \ mol \ Zn(\frac{1 \ mol \ Fe}{1 \ mol \ Zn} )$ = 7 mol Fe

Step 3: Check

We are given 1 sig fig.

Since our final answer is in 1 sig fig, there is no need to round.

A student prepares a solution by dissolving 60.00 g of glucose (molar mass 180.2 g mol-1) in enough distilled water to make 250.

anyanavicka [17]

Answer:

1.332 Molar is the molarity of the glucose solution.

Explanation:

Molarity of the solution is the moles of compound in 1 Liter solutions.

$Molarity=\frac{\text{Mass of compound}}{\text{Molar mas of compound}\times Volume (L)}$

Mass of glucose = 60.00 g

Molar mass of glucose = 180.2 g/mol

Volume of the solution = V = 250.0 mL = 0.250 L

(1 mL = 0.001 L)

$Molarity=\frac{60.00 g}{180.2 g/mol\times 0.250 L}=1.332 mol/L$

1.332 Molar is the molarity of the glucose solution.
