Answer :
When using the formula: n = m / M
n = moles
m = mass (g)
M = molar mass (g mol^-1)
The answer is C) 638
n = moles
m = mass (g)
M = molar mass (g mol^-1)
The answer is C) 638
When using the formula: n = mass / Molar mass
n = moles
m = mass (g)
M = molar mass (g mol^-1)
What is mass?
Mass is a measure of the amount of matter that an object contains. The base SI unit of mass is the kilogram or kg, which was originally defined as the mass of 1L of liquid water at 40 degree C (the volume of a liquid changes slightly with temperature).
Mass 6.50 = mass / 98 mass=637g
6.5 moles of H2SO4 weighs 637g.
Hence, the correct option is 638g.
