Answer:
1.8g
Explanation:
Initial volume = 43.5ml
Final volume = 49.4ml
Mass = 10.88g
Density = ?
Volume = Final volume - initial volume
= 49.4 - 43.5
= 5.9ml
Density = Mass/volume
Density = 10.88/5.9
= 1.8g/ml
Hey there!:
* For 2p subshell :
n = 2, l =1, ml = -1, 0, +1
* for 5d subshell,
n = 5, l = 2, ml = -2, -1, 0, +1, +2
Hope that helps!
The average atomic mass of the element = 35.5
calculation
average atomic mass = sum of the masses of its isotope each multiplied by its natural abundance.
that is
[(75 x35) +(25 x37)] /100 = 35.5
