Chemistry: Diamond is one form of elemental carbon engagement ring contains a diamond weighing 1.25 carats (1 carat is equal to 200 mg). ? ow many atoms are present in the diamond.

Both are correct. They can review executive and legislative acts :)...

$1.29x10^{22} atoms$

Explanation:

First of all we need to dererminate the diamond mass by transforming carats in grams

$1.25_{carat} *0.200_{g/carat} = 0.250_{g}$

Upon consulting a periodic table one finds the atomic mass of carbon

C=12.01 g/mol

Knowing the carbon mass and the avogrado constant (1 mole = $6.022x10^{22} atoms$ ) one compute how many atoms there are in 0.250 g of diamond

$0.250_{g}/12.01_{g/mol}*6.022x10^{22}_{atoms/mol}=1.29x10^{22}_{atoms}$
