The number of particles= 1.43 x 10²⁴ particles
<h3>Further explanation</h3>
Given
53.2 L volume of gas at STP
Required
The number of particles
Solution
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters/mol.
So mol for 53.2 L :
= 53.2/22.4
= 2.375 moles
1 mol = 6.02 x 10²³ particles (molecules, atoms, ions)
The number of paricles for 2.375 moles gas :
= 2.375 x 6.02 x 10²³
= 1.43 x 10²⁴ particles

Answer:
in contact
Explanation:
Fields allow some objects to exert force on each other even when they are not contact with one another.
The region of space where the effect of a force is felt is know as a field.
- Field forces for provides a non-contact means of exerting forces.
- They objects do not have to be in contact before the force is felt.
- An example is the gravitational force field.
Answer:
1.75moles
Explanation:
Molarity = number of moles (n) ÷ volume (V)
According to the information given in this question,
V = 500mL = 500/1000 = 0.500L
n = ?
Molarity = 3.5M
Using Molarity = n/V
number of moles (n) = V × molarity
n = 0.5 × 3.5
n = 1.75moles.
