Question

I have 500. mL of a gas, what volume is this in liters? (enter your numerical answer with correct sig. figs. and without units in the box below.)

Answer 1

Answer:0.50

Explanation:In carrying out multiplication/division, the answer cannot have more significant figures than either of the original numbers.

mL=*10E-3=*0.010L(2 significant figures)

500=3 significant figures

500mL=(500E-3)L=500*0.010L=0.50

N/B:500E-3 =500 raised to the power of -3.
