this is over significant digits.
-Indicate how many significant figures are in each of the following measurements:
e) 4.0 X 10-5 kg
i got 1 significant digit, but i'm not sure it if it's right... (& i can't ask my teacher, the situation is complicated)
nope, the 0 tothe right of a decimal is significant. 2 sig digits.
