6 How many moles are in a 321 g sample of magnesium? F 13.2 mol Mg
G 13.4 mol Mg
H 13.6 mol Mg
J 13.8 mol Mg

13.4mol of Mg

Explanation:

Given parameters:

Mass of magnesium = 321g

Unknown:

Number of moles  = ?

Solution:

The number of moles of a substance is given as;

  Number of moles  =  

 Molar mass of Mg = 24g/mol

 Insert the parameters and solve;

        Number of moles  =   = 13.4mol of Mg

you should just be yourself and not let any body tell you other wise.

explanation:

why?

because if they don't love you for your self then they don't deserve you.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
