9.00g/1hr * 1kg/100g * 1hr/60min = 0.00015kg/min or 1.5 * 10^-4kg/min.
MAGNESIUM(Mg) posses the up mentioned electronic configuration
What do you mean I don’t understand this I could help but don’t understand
Answer:
70.92u
Explanation:
The atomic mass expresed at fisrt (69.7u) is a combination of the atomic masses of both isotopes multiplied by their natural abundance. So we can describe "(68.9*.604)+(x*.396)=69.7" the as the equation neccesary to solve this problem, where x is the atomic mass of gallium-71. x=70.92.
