How many Significant figures does each answer have? explain why did you consider that number? exact number or measured?
a = 8 moles * 3.5 l / 4 moles
= 7 litres
answer = 7 (only one significant figure)
b = 20.0 L * 500c / 250c
= 40 litres (2 significant figures)
c = V1 30.0 L
=> V2 = 2* V1
= 2*30
= 60 litres (2 significant figures)
based on the no of digits obtained after the calculation will give the correct significant figures
