Let x be the mass of the ore in grams such that the equation that would allow us to answer this item would be,
55 = (x)(0.243)
The value of x is calculated as,
x = 55/0.243
x = 226.337 grams
Then, solve for amount in kilograms by dividing the calculated value by 1000. This methodology will give us an answer of 0.226337. Hence, the answer is 0.226.
