a chemist needs to know the mass of a sample of caco3 to 2 significant digits. he puts the sample on a digital scale. this is what the scale shows: 0 0 0 2 4 . 0 g if this measurement is precise enough for the chemist, round it to 2 significant digits.



Answer :

The mass of the CaCo3 to 2 significant numbers = 24 g

In any type of scientific dimension, the perfection of the dimension is represented in the significant integers of that dimension. It also used to show the dimension to the necessary degree of delicacy.

Significant integers comprises every number except the leading zero( s). And if the number after the needed significant integers isn't over to 5, it's rounded down and the needed significant integers is written as is. But if the number after the needed significant integers is at least 5, it rounded up, and the last number on the significant integers demand is increased by a factor of 1.

Exemplifications include :

0.3547 = 0.355 to 3s.f(0.0007 is rounded up to increase the coming number, 4, by a factor of 1)

Hence, the answer would be 24 g
