Explanation:
Answer:
The mass of nickel is 48μg
Explanation:
Parts per billion is a way to describe small concentrations and is defined as the ratio between μg of solute and kg of solvent.
If a solution of nickel in propanol is 20ppb, contains 20μg of nickel in 1 kg of propanol.
Thus, a sample of 2.4kg of propanol will contain:
2.4kg × (20μg nickel / 1kg) = 48μg nickel
<h3>The mass of nickel is 48μg</h3>
Five base SI units that are commonly used in Chemistry; are
1.Metre (m)
2. Kilogram(kg)
3. seconds(s)
4.Kelvins (k)
5. Moles (mol)
I’m not 100% sure lol but I’ll say D
