The united stated chemical industry produces more sulfuric acid, in terms of mass, than any other chemical. What is the mass of
3.25 moles of sulfuric acid. Please show work!!!
2 answers:
The chemical formula for sulphuric acid is H2SO4
The molar mass of H2SO4 is calculated as;
2(1)+32+4(16)
98g/mol
Amount of substance =mass/molar mass
Mass=Molar mass*Amount if substance
Mass=98*3.25
Mass=318.5g
I hope this helps
Answer:
318.749g
Explanation:
The find the mass,
We use this formula
Number of mole = mass/ molar mass
Since number of mole = 3.25mol
Let the number of mass be x
The 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
x= 318.749g
Hence, the number of mass is 318.749g
Hope it will help you.

D. All of the answers are true
The volume of a gas that its pressure increase to 3.4 atm is calculated as follows
By use of boyles law that is P1V1=P2V2
V1=4.0 L
P1=1.1 atm
P2=3.4 atm
V2= P1V1/P2
(1.1 atm x 4.0 L)/3.4 atm= 1.29 L
Isn't that Hund's rule????
Explanation:
m=5g
density=1.25g/ml
density=m/v
v=m/density=5/1.25
