Different Units Can Be Used for Length: M and Cm,and

Different units can be used for length: m and cm,and of these two,m is the larger by a factor of 100.Different units can also be used for R:
(1) J/mol⋅K,
(2) L⋅atm/mol⋅K,and
(3) (N/m²) ⋅m³/mol⋅K.
Which of these units for R is the largest? Hint: When expressing R in each of these units,which expression has the lowest numerical factor? (1 L = 10−³ m³,1 atm = 1.01 × 10⁵ Pa)

A) 1
B) 2
C) 3
D) They are all equal.
