The product of the measurements 2.05 cm x 32 cm should be rounded to

Chemistry
1 answer:
Bas_tet [7]3 years ago
7 0

Answer:

Two significant figures

Step-by-step explanation:

In <em>multiplication </em>problems, your answer can have no more significant figures than the number with the <em>fewest significant figures</em>.

2.05 cm × 32 cm = 65.600 000 00 cm² (by my calculator)

There are three significant figures in 2.05, but only two in 32.

You must round to <em>two</em> significant figures and report the answer as 66 cm².

65.600 000 00 cm² ⟶ 66 cm²
