Question

A mole is a unit like a dozen. Calculate the number of dogs in 3.32x10⁻24 mol of dog using the Avogadro's number (1 mol = 6.02214x10²3).

a) 1.998x10⁻¹ dogs
b) 1.998x10²³ dogs
c) 1.998x10¹ dogs
d) 1.998x10⁻²³ dogs

Answer 1

To calculate the number of dogs in 3.32x10^-24 mol of dog using Avogadro's number, you can multiply the amount of substance by Avogadro's number.

Step-by-step explanation:

To calculate the number of dogs in 3.32x10-24 mol of dog using Avogadro's number, we need to use the conversion factor:

1 mol = 6.02214x1023 dogs

Given:

Amount of substance = 3.32x10-24 mol

Avogadro's number = 6.02214x1023 dogs/1 mol

To find the number of dogs, we can multiply the amount of substance by Avogadro's number:

Number of dogs = 3.32x10-24 mol x (6.02214x1023 dogs/1 mol)

Solving the expression, we get:

Number of dogs = 1.998x100 dogs
