3 0

Answer:

Find the element,

Explanation:

Finding the element will tell you how many protons there are. For example, if you are given an atom of oxygen, you can figure out the number of protons by looking it up on a periodic table, which gives you 8.

If an atom is neutral, find the number of electrons. This number will also be the number of protons.

Answer:

24.47 L

Explanation:

Using the general gas law equation:

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = 0.0821 Latm/molK

T = temperature (K)

According to the provided information in this question,

P = 1.0 atm

V = ?

n = 1 mol

T = 25°C = 25 + 273 = 298K

Using PV = nRT

V = nRT ÷ P

V = 1 × 0.0821 × 298 ÷ 1

V = 24.465 ÷ 1

V = 24.465

V = 24.47 L
