Which balance is the centigram balance? 1) a2) b

It is B balance, because it has a 0,01 g divisions scale. The minimun division in A balance is only 0,1 g, i.e, decigram measurement.

B

Explanation: 1 gram equals to 100 centigrams. We can also say that, 1 centigram equals to 0.01 gram.

From above centigram to gram conversion factor, there are two decimal places in 0.01 gram. So, a centigram balance is the one that could read the mass of a matter(object) to two decimal places.

Balance A can only read to one decimal place where as balance B can read the mass up to two decimal places.

Hence, balance B is the centigram balance.
