Four.
No, it actually has seven significant figures. Basic rule: (1)When number has decimal point---count from left to right counting all numbers after the first non-zero number ex.-->.009367 has 4 sig figs ex.-->9.367 has 4 sig figs ex.-->9.367000 has 7 sig figs (2)When number doesn't have a decimal point---count right to left counting all numbers after the first non-zero number ex.-->12 has 2 sig figs ex.-->120 has 2 sig figs ex.-->1207800 has 5 sig figs
It is an ambiguous question. The answer is 2, 3, 4 or 5. If counting in thousands: 43000, 44000, 45000 then 2 at the other extreme, if counting in units: 44998, 44999, 45000 then 5.
