Explanation:
It is known that number of moles is equal to the mass divided by molar mass of a substance.
Mathematically, No. of moles = [tex]\frac{mass}{\text{molar mass}}[/tex]
Since it is given that number of moles is 0.80 mol and molar mass of [tex]H_{2}CO_{3}[/tex] is 62.03 g/mol.
Therefore, we can conclude that mass of [tex]H_{2}CO_{3}[/tex] is as follows.
No. of moles = [tex]\frac{mass}{\text{molar mass}}[/tex]
0.80 mol = [tex]\frac{mass}{62.03 g/mol}[/tex]
mass = 49.62 g
Thus, we can conclude that mass in grams of 0.800 mole of [tex]H_{2}CO_{3}[/tex] is 49.62 g.
