Stainless steel contains 12.1% nickel. Find the mass of nickel in a 5kg steel ingot.

Brief entry:
In steel – 12.1% nickel;
Steel weight – 5 kg.;
Nickel mass =?
Solution:
To find the specified percentage of a given number, you need to multiply this number by the number of percent and divide the result by 100.
Then the mass of nickel is 5 kg. became equal to:
5 * 12.1: 100 = 60.5: 100 = 0.605 (kg.);
For ease of reading, let’s express kilograms in grams;
1 kg. = 1000 g;
0.605 kg. = 605 g.
Answer: 605;
