Answer:
Explanation:
When going from top to bottom in any group of the periodic table, the atomic radius always tends to increase
I personally think that it’s C.
(i’m sorry if it’s wrong)
Mass of block, m = 5.26 lb
1 lb = 453.592 g
5.26 lb = 2385.896 g
V = 14 in3
1 in = 2.5 cm
1 in3 = 15.625 cm3
14 in3 = 218.75 cm3
Density = mass/volume
= 2358.896 / 218.75
= 10.783 g/cm3
It’s option B 0.0821L.atm/mol.K
3.3256 Liters
