Which of the following DOES NOT have 2 significant figures?
0.0000011
11,000,000,000
l0.11
1.001

Significant figures are the digits that come after the first non-zero digit. The second value has 11 significant figures and is therefore the correct answer. However, the fourth answer has 4 significant figures and would also be a correct answer. So I don’t know if perhaps there has been a typo or a mistake in the question but with what you have provided here, both these answer have more than 2 significant figures.

Idon't know hope someone you
