Answer:
the acceleration i think is 8
Explanation:
50+5x8
To calculate the mass, go from atoms to moles and moles to grams:
Atoms ........ Moles.......... Grams
From atoms to moles, use the Avogadro’s no. which is 6.022 x
10^23 and from moles to grams use atomic mass of Pt that is 195.08g.
So, 4.91 x 10^21 Pt atoms x (1 mole Pt / 6.022x10^23 Pt atoms) x (195.08g Pt
/ 1 mole Pt) = 1.59g Pt
Mass of 4.91 x 10^21 Pt atoms = 1.59g Pt
They are not closely packed or arranged orderly.
Hope this helps!
