Question

5. Give the number of significant figures in each of the following.

a) 1.05 g
b) 0.0003040 mm
c) 29000 + 10 ft
d) 0.90 x 1045 L
e) the number of eggs (12) that make up a dozen

Answer 1

a) 3 sig figs

b - d) 4 sig figs

e) 2 sig figs

Step-by-step explanation:

When it comes to sig figs natural numbers count. Zeros only count when thay are in between natural numbers. For example 1.05 g has 3 sig figs and they are 1, 0, and 5. And 0.0003040 mm has 4 sig figs since the 4 trailing zeros before the 3 don't count.
