Question

how many decimal places could you record using a 100ml graduated cylinder, a 250ml beaker, a 10ml graduated cylinder and a buret ?

Answer 1

the rule is that

we can estimate one more digit past the smallest division on the measuring device

1)

consider the 100mL graduated cylinder

we know that

the smallest graduation is a milliliter ( 1 ml)

we can measure one more digit past 1

it means we can estimate to the tenths place (0.1mL)

So

for a 100 ml graduated cylinder we can estimate upto 1 decimal point

2)

consider the 250mL beaker

the smallest graduation is 25 ml

we can measure one more digit past 25

it means we can estimate to the units digit

So

for a 250 ml graduated cylinder we cannot estimate upto decimals

3)

now

consider the 10mL graduated cylinder

the smallest graduation is tenth of a milliliter (0.1mL).

we can measure one more digit past 0.1

it means we can estimate to the hundredths place (0.01mL)

So

for a 10 ml graduated cylinder we can estimate upto 2 decimals

4)

consider the 10mL burette

the smallest graduation is tenth of a milliliter (0.1mL).

we can measure one more digit past 0.1

it means we can estimate to the hundredths place (0.01mL)

So

for a 10 ml burette we can estimate upto 2 decimals
