Question

Number of representative particles in 0.250 mol silver

Answer 1

A mole is just a specific number = 6.022 x 10^23 {actually this is approximately the number}. So one mole of a particular thing is 6.022 x 10^23 of those things. In a 0.250 mole silver = 0.250 (6.022 x 10^23) silver = 1.506 x 10^23 silver.

Answer 2

Answer: The number of representative particles in the given amount of silver are
`1.506* 10^(23)`

Step-by-step explanation:

We are given:

Moles of silver = 0.250 moles

According to mole concept:

1 mole of an element contains
`6.022* 10^(23)` number of atoms

So, 0.250 moles of silver will contain =
`(0.250* 6.022* 10^(23))=1.506* 10^(23)` number of atoms.

Hence, the number of representative particles in the given amount of silver are
`1.506* 10^(23)`
