Which mass measurement contain s four significant figureS?..
0.0086 g, 0.431 g, 1003 g, 3870 g

Answer 1

1003g & 3870g

Answer 2

the last 2 -1003 g & 3870 g
0.0086 has 2
0.431 has 3

Answer 3

1003g, the two zeros count in this instance because it is in between two nonzero digits.
in 0.0086 there are only 2 sig figs, the zeros preceding it don't count, same is true with 0.431 (3 sig figs, zero doesn't count).
3870 only has 3 sig figs because the zero does not have a decimal after it. if it were 3870. then it would have 4 sig figs.
