Answer:

6.8 mole of O₂

Explanation:

Given expression:

2H₂ + O₂ → 2H₂O

Number of moles of H₂ = 13.6moles

Unknown:

Number of moles of O₂ = ?

Solution:

In the given problem, we are to find the number of moles of oxygen gas that will use up 13.6mole of hydrogen gas;

From the reaction equation;

2 mole of H₂ will completely react with 1 mole of O₂

13.6 moles of H₂ will completely be used up by $\frac{13.6}{2}$ mole of O₂

= 6.8 mole of O₂

How many decigrams are in 4.6 decagrams?

11111nata11111 [884]

Answer:

$\large \boxed{\text{460 dg}}$

Explanation:

1. Convert decagrams to grams

$\text{Mass} = \text{4.6 dag} \times\dfrac{\text{10 g}}{\text{1 dag}} = \text{46 g}$

2. Convert grams to decigrams

\ $\text{Mass} = \text{46 g} \times\dfrac{\text{10 g}}{\text{1 dg}} = \text{460 dg}\\\\\large \boxed{\textbf{4.6 dag = 460 dg}}$
