1.6700 * 104 grams or 1.67*104 grams if the trailing 0s are not significant digits.
1.5*104 = 104(3)(.5) = 312/2 = 156. 3 digits.
It depends on how many significant digits you require; assuming 3 it's 1.82x10^41.82 x 104

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.". Note that the zero has to be made significant, so a decimal point is needed after the zero or you could put a vinculum (horizontal line) above the zero.
There are 5 significant digits in 78000. Which is the same as 7.8 x 104.
1.6700 * 104 grams or 1.67*104 grams if the trailing 0s are not significant digits.
1.5*104 = 104(3)(.5) = 312/2 = 156. 3 digits.

104 in 2 significant figures is 1.0e2
Assuming that the number in question is 7.99*104, the answer is 3.
104 = 10000 if digits can be repeated, 5040 if not. The above answers assume a code can start with a 0. If not, 9000 if digits can be repeated and 4536 if not.
