<u>Answer:</u> The correct answer is Option c.

<u>Explanation:</u>

According to mole concept:

1 mole of an element or compound contains 6.022\time 10^{23} number of particles.

The number is called as Avogadro's number.

We are given:

One mole of a copper element

This element will have the Avogadro's number of particles which is 6.02\times 10^{23}

Hence, the correct answer is Option c.

If you have a density of 100 kg/L and a mass of 1000 g what is the volume (please explain)
olchik [2.2K]

Answer:  Volume =  0.01L

Explanation:

The density of a substance is given by; Density =  Mass / Volume.

In this question, Mass = 1000g, Volume = ? and Density = 100 Kg/L

For the units to be uniform, we convert 1000g to Kg = 1Kg

Therefore, Volume = Mass / Density =  1Kg / 100Kg/L = 0.01L
