The following masses are given in kilograms. Use metric prefixes on the gram to rewrite them so the numerical value is bigger than one but less than 1000. For example, 7*10^-4kg could be written as 70 cg or 700 mg.

(a) 3.8*10^-5kg

(b) 2.3*10^17kg

(c) 2.4*10^-11kg

(d) 8*10^15kg

(e) 4.2*10^-3kg.

a) 38 mg

b) 230 Exa-g

c) 24 ng

d) 8 Eg

e) 4.2 g

Step-by-step explanation:

Given:

a) 3.8*10⁻⁵ kg

1 kg = 10⁶ mg

Multiply the above value by 10⁶

we get

3.8*10⁻⁵ * 10⁶ = 38 mg

b) 2.3 * 10¹⁷ kg

or

2.3 * 10²⁰ g

1 exa = 10¹⁸

multiply by 10⁻¹⁸

we get

230 Exa-g

c) 2.4 * 10⁻¹¹ kg

or

24 * 10⁻⁹ g

1 g = 10⁹ ng

thus,

24 * 10⁻⁹ g * 10⁹ = 24 ng

d) 8*10¹⁵ kg

or

8 * 10¹⁸ g

1 exa gram = 10¹⁸ g

(8 * 10¹⁸) * 10⁻¹⁸ = 8 Eg

e) 4.2 * 10⁻³ kg

or

4.2 * 10⁻³ * 10³ = 4.2 g
