Calculate the number of moles of Cl atoms in 3.01×1024 formula units of magnesium chloride, MgCl2.
natta225 [31]
Answer: 10 moles
To find how many moles, you need to divide the number of atoms with 6.02 * 10^23. Since every magnesium chloride has two chlorine atoms, you need to multiply it by 2. The calculation would be:  3.01×10^24  * 2 / 6.02 * 10^23= 10 moles

Soloha48 [4]

Answer:

It won't change.

-26F=3.33C

Explanation:

The pressure won't change since the system is closed and its volume is the exact same, the only way to change the tanks pressure is to open or pump more gas into or changing the temperature.

- To convert Fahrenheit to Celsius, you need to subtract 32 and divide by 1.8, in the next equation will substitute 26 F.

C=(F-32)\1.8

C=(26-32)\1.8

C=-3.33

I hope you find this information useful and interesting, good luck!
