Answer:
(a) 1.
(b) 4.
(c) 3.
(d) 2.
Explanation:
Hello,
(a) In this case, we do no take into account the zero digits before the first nonzero digit which is three, therefore it has one significant figure.
(b) In this case, we consider all the given figures since they are all after the first nonzero digit, therefore it has four significant figures.
(c) In this case, we consider all the given figures since they are all after the first nonzero digit including the decimal place, therefore it has three significant figures.
(d) In this case, we consider all the given figures since they are all after the first nonzero digit, therefore it has two significant figures.
Regards.
Create your conversion factors.
You know that 1 micrometer = 1/1000000 m
Then,
[1 micrometer]^2 =[1/1000000 m]^2 =>
=> 1 = [1000000]^2 micrometer^2 / m^2
Now multiply the given area times your conversion factor:
1.50 (micrometer)^2 * [1/1000000]^2 micrometer^2 / m^2 = 1.50*10^(-12) m^2
Answer: 1.50*10^(-12) m^2
Between 1.00 & 1.5 grams would be the normal amount
