<u>Stoichiometry</u>

Using Dimensional Analysis

<h3>Explanation:</h3>

<u>Step 1: Define</u>

3.01 × 10²⁴ atoms O₂

<u>Step 2: Identify Conversions</u>

Avogadro's Number

<u>Step 3: Convert</u>

Set up: $\displaystyle 3.01 \cdot 10^{24} \ atoms \ O_2(\frac{1 \ mol \ O_2}{6.022 \cdot 10^{23} \ atoms \ O_2})$
Multiply/Divide: $\displaystyle 4.99834 \ mol \ O_2$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

4.99834 mol O₂ ≈ 5.00 mol O₂

If i have a 50 L container that holds 45 moles of gas at a temperature of 473 K, what is the pressure inside the container?

Furkat [3]

Answer:

The pressure inside the container is 34.97 atm

Explanation:

Given:

V=50L R= 0.0821LatmK^-1mol^-1

n= 45mol T= 473k

PV=nRT

P= nRT/V

= 45mol*0.0821Latmmol^-1K^-1*473K/ 50L

=34.95atm

Which of the following are likely to form a covalent bond?

harkovskaia [24]

Answer:

• Hydrogen and oxygen atoms

Explanation:

Hydrogen and oxygen are nonmetals. They are most likely to share electrons and form a covalent bond.

A is wrong. Gold is a metal, so it will form metallic bonds.

O is wrong. Neon is a noble gas. It has a complete octet, so it is unlikely to form covalent bonds.

D is wrong. Mg is a metal, and Br is a nonmetal. They are more likely to form ionic bonds.
