I got B. Because the answer is K2SO4, I got it right on my test so I know its right
Using Avogadros number, we can get that 1 mole of an atom
contain 6.022 x 10^23 atoms. Therefore we can use this conversion factor to get
the number of moles:
moles ZnCO3 = 6.11 x 10^22 atoms * (1 mole / 6.022 x 10^23
atoms) = 0.10146 moles
The molar mass of ZnCO3 is about 125.39 g/mol, therefore the
mass is:
mass ZnCO3 = 0.10146 moles * (125.39 g / mol)
<span>mass ZnCO3 = 12.72 g</span>
Momentum and Kinetic Energy...They both are directly proportional to the
Mass and Velocity of the object and they are the only factors which
determine them.
Hope this helps!
<span>. They make sure their experiments can be repeated</span>
