How many significant figures are in 25.030 , 0.006 070 , 1.004 and 1.3005 20 and why ?

25.030: 5 because zeroes are after decimal

0.006: 3 because 2 zeroes are after decimal

1.004: 4 because zeroes are between numbers

(Not sure what you meant to write for these)

1.300520: 7

1.3005: 5 because zeroes are after decimal and between numbers

20: 1 because zero isn't after a decimal or between numbers

Numbers other than 0 are always SigFigs!

Hope I helped! :)

Answer:

Explanation:

The significant figures are defined as the figures that give the value and information of the accuracy of a measurement. The zero is the number that can have two behaviors if it is to the right of us numbers is significant since it gives an idea of the precision of the meditation, but if it is on the left and only serves to indicate the position of the decimal point it is not significant ; All of us numbers are always significant.

Using the above statements we will shrink the significant numbers numbers:

25.030 5 all significant, zero right indicates measurement accuracy

0.006070 4 zeros to the left of the “6” indicate position of the decimal point, they are not significant

1,004 4 all significant

1.300520 7 all significant, zero right indicates accuracy is significant
