Answer/ explanation :
The find the mass,
We use this formula
Number of mole = mass/ molar mass
Since number of mole = 3.25mol
Number of mass be x
Molar mass of H2SO4
H - 1.00784 * 2= 2.01568
S - 32.065
O - 15.999 * 4 = 63.996
Note there are 2 moles of H and 4 moles of O and 1 mole of S
Molar mass of H2SO4 = 2.01568 + 32.065 + 63.996
= 98.07668g/mol
Number of mole= 3.25mol
3.25 = x / 98.07668
x = 3.25 * 98.07668
= 318.749g
Therefore, the number of mass is 318.749g
Answer:
For simplicity lets round everything to the 3rd sigfig
H = 1.01g
S = 32.1g
O = 16.0g
H2SO4 implies there are two H and 4 O
with this known you can simply multiply the masses of these two elements by the amount
(1.01g * 2) + 32.1g + (16.0g * 4) = 319g H2SO4
