The compound that has higher mass percent is Mg3N2 which is 72%

explanation
calculate the % mass of Mg in each compound

% composition of mg= molar mass of Mg/ total molar mass of the compound x100

in MgO = 24 /40 x100 = 60%

in Mg3N2 =72/100 x100 = 72 %

therefore the % composition in Mg3N2 is higher

cestrela7 [59]

Answer:

The number of moles of salt in one tablespoon is = <u>0.11 mole</u>

<u>Grams </u>cancel each other.

Explanation:

<u>Moles</u> : It is the unit of quantity . It is the mass of the substance present in exactly 12g of C-12.

$moles=\frac{given\ mass}{Molar\ mass}$

<u>Moles Calculation:</u>

Given mass = 6.37 gram

Molar mass = 58.5 g/mol

$moles=\frac{6.37}{58.5}$

= 0.1088

= 0.11 mole

<u>Units calculation</u>

$moles=\frac{given\ mass}{Molar\ mass}$

$moles=\frac{g}{g/mole}$

$moles=\frac{g}{g}\times mole$

<u>g ang g cancels each other </u>

moles = moles

<u>Hence unit = gram (g ) cancel each other.</u>
