hope it 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.
Uh to warn you it doesn't show anything on here=(
Answer:
The equation for Kinetic Energy is: KE = 1/2 mv2. Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the Kinetic Energy of an object. The same is true of velocity. However, mass and velocity are indirectly related.
Answer:
A. It keeps the electrolyte solutions neutral.
Explanation:
The electrons flow from the anode to the cathode and the problem is that the cathode may become too negative. The purpose of the salt bridge is to maintain charge balance because the electrons are moving from one-half cell to the other.
