6 of them.
There are 5 significant digits in 78000. Which is the same as 7.8 x 104.
3. Captured zeros (zeros between two other significantnumbers) are always significant.
0.0310 has 3 significant figures.
2.5000 has five significant digits and 104 has three significant digits. Therefore, the product should have three significant digits, and the answer is "260.".
