We need to find the mass in grams in$2.28$ moles .

Here one mole is atomic mass of substance expressed in grams .

Number of moles=gram molecular weight/molar mass .

So we are given with the number of moles , we know molar mass of substance.

Therefore mass in grams is $2.28\cancel{moles}×28\frac{g}{\cancel{moles}}=63.84$g

We need to find the mass in grams in $2.28$moles .

Here one mole is atomic mass of substance expressed in grams .

Number of moles=gram molecular weight/molar mass

So we are given with the number of moles , we know molar mass of substance.

Therefore mass in grams is$2.28\cancel{moles}×80.06\frac{g}{\cancel{moles}}=182.53$g

We need to find the mass in grams in $2.28$moles .

Here one mole is atomic mass of substance expressed in grams .

Number of moles=gram molecular weight/molar mass

So we are given with the number of moles , we know molar mass of substance.

Therefore mass in grams is$2.28\cancel{moles}×90.08\frac{g}{\cancel{moles}}=205.38$g

We need to find the mass in grams in $2.28$moles .

Here one mole is atomic mass of substance expressed in grams .

Number of moles=gram molecular weight/molar mass

So we are given with the number of moles , we know molar mass of substance.

Therefore mass in grams is$2.28\cancel{moles}×146.34\frac{g}{\cancel{moles}}=333.6$
