How many significant figures are there in the measurement 50,600 mg?

Answer 1

#3# significant figures.

In any number figure, the number of digits in the figure that are important in determining its value are called significant.

Zeros are included only if they contribute to the value of the number. Zeros before the first significant digit, if to the left of decimal point are ignored and similarly zeros to the right of number after decimal point are not included.

In the number #50600#, we have first three significant digits. However, had it been #00050600#, first three zeros too would have been ignored and similarly in #50600.00# last two zeros are not significant.
