LaoTo calculate the amount of NH3 needed to react with 21 grams of CH3OH, you first need to balance the chemical equation for the reaction. Then, you convert the mass of CH3OH to moles and use the mole ratio from the balanced equation to determine the moles of NH3 required. Finally, convert the moles of NH3 to grams using the molar mass of NH3.

How many grams of antimatter are needed to react with 5 g of matter?
Exactly 5 grams of antimatter will completely annihilate 5 grams of matter, producing an enormous shower of high energy gamma rays. In total a mass of 10 grams will be converted to the equivalent amount of energy.
How many grams of bromine are required to completely react with 22.1 g of titanium?
The molar mass of titanium is 47.87 g/mol and the molar mass of bromine is 79.90 g/mol. Titanium reacts with two moles of bromine, so you would need 2 moles of bromine per mole of titanium. Using the molar masses of both elements, you can calculate the grams of bromine needed to react with 22.1 g of titanium.
What is the equilvalent weight?
Equivalent weight is the mass of a substance that will react with or replace one mole of hydrogen ions (H+) in an acid-base reaction or one mole of electrons in a redox reaction. It is used in stoichiometry calculations to determine the amount of a substance needed for a reaction.
How many grams of Fe3O4 are required to react completey with 300 grams of H2?
The balanced chemical equation for the reaction between Fe3O4 and H2 is: Fe3O4 + 4H2 -> 3Fe + 4H2O From the equation, it can be seen that 1 mole of Fe3O4 reacts with 4 moles of H2. Calculate the moles of H2 in 300g, then use the mole ratio to find the moles of Fe3O4 needed. Finally, convert the moles of Fe3O4 to grams using its molar mass to determine the amount required.
How many grams of oxygen are needed to react with 2.5 grams of dihydrogen sulfide?
The molar ratio of oxygen to dihydrogen sulfide in the reaction is 3:1. First, find the number of moles of dihydrogen sulfide by dividing its mass by its molar mass. Then, use the mole ratio to calculate the moles of oxygen needed. Finally, convert the moles of oxygen to grams.
