CHEM HELP!

sweet [91]

So let's convert this amount of mL to grams:

$\frac{13.6g}{1mL}*1.2mL=16.32g$

Then we need to convert to moles using the molar weight found on the periodic table for mercury (Hg):

$\frac{1mole}{200.59g}*16.32g=8.135*10^{-2}mol$

Then we need to convert moles to atoms using Avogadro's number:

$\frac{6.022*10^{23}atoms}{1mole} *[8.135*10^{-2}mol]=4.90*10^{22}atoms$

So now we know that in 1.2 mL of liquid mercury, there are $4.90*10^{22}atoms$ present.

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
