one thousand grams of beryllium and 3000 grams of other elements made up the mixture. If 24,000 kg of the mixture was needed, how much beryllium was required?
I start by converting kg to g, and creating two equations.
1,000g(X) + 3,000g(Y) = 24,000,000g
X = Y
X and Y = 6000
1,000g(6000) + 3,000g(6000) = 24,000,000g
Therefore, 6,000,000g (or 600kg) of Beryllium is required to create 24,000kg of the mixture.
