Question

How many moles are equal to 2.4×10^23 formula units of sodium chloride

Answer 1

There are 6.022 x 10^23 formula units per mole

2.41 x 10^24 / 6.022 x 10^23 = 4.00 moles

Answer 2

Answer: The number of moles of sodium chloride are 0.40 moles

Step-by-step explanation:

We are given:

Number of formula units =
`2.4* 10^(23)`

According to mole concept:

`6.022* 10^(23)` number of formula units are contained in 1 mole of a substance

So,
`2.4* 10^(23)` number of formula units will be contained in
`(1)/(6.022* 10^(23))* 2.4* 10^(23)=0.40` moles of sodium chloride

Hence, the number of moles of sodium chloride are 0.40 moles
