How much is 2400 tonnes?

2400 tonnes (metric tons) equates to 5,290,000 pounds or 2,650 US tons.


In a reaction 25 grams of reactant AB breaks down into 10 grams of product A and an unknown amount of product B. Using the law of conservation of mass how much does product B weigh?

According to the law of conservation of mass, the total mass of reactants must equal the total mass of products. In this case, the initial mass of reactant AB is 25 grams, and product A weighs 10 grams. Therefore, the mass of product B can be calculated as follows: 25 grams (mass of AB) - 10 grams (mass of A) = 15 grams. Thus, product B weighs 15 grams.


If the mass of the container is 14.5 grams what is the mass of the sand?

To determine the mass of the sand, you'll need to subtract the mass of the container (14.5 grams) from the total mass of the container with sand in it. For example, if the total mass of the container with sand is 50 grams, then the mass of the sand would be 50 grams - 14.5 grams = 35.5 grams.


What is the mass of the powder if the combined mass of the powder and its container is 12 grams and the mass of the container alone is 4 grams?

The mass of the powder is 8 grams. This can be calculated by subtracting the mass of the container (4 grams) from the combined mass of the powder and container (12 grams), leaving the mass of the powder as 8 grams.


What is the mass of a powder if the combined mass of the powder and its container is 12 grams and the mass of the container alone is 4 grams?

The mass of the powder is 8 grams. This can be calculated by subtracting the mass of the container (4 grams) from the total mass of the powder and container (12 grams).
