Tonnage is commonly known as 1 ton, and the product contains 1% of the specified components. For molybdenum concentrate, the price of 2000 yuan/ton is equivalent to:

2000 yuan /( 1t * 1%)=2000 yuan /( 1000 kg * 1%)=200 yuan /kg molybdenum.

The domestic benchmark content is set at 45%, which can also be said to be 45 tons of products, and the price is 45 times that of 1 ton.

45% molybdenum concentrate 100t price =2000 yuan/ton * 45t *100 = 9 million = 9 million.

You can also calculate it like this:

100 ton 45% molybdenum concentrate price =200 yuan/kg molybdenum *( 100* 1000 kg * 45%) = 9 million.

Foreign quotations are generally 1 kg molybdenum or 1 lb molybdenum, which is much easier to understand.
