We can prepare the reagent by weighing out the amount equal to the number of moles required for a substance multiplied to its molar mass.Answer and Explanation: Determine the mass, m, of the given amount of water. We do this by simply multiplying the given number of moles, n = 0.85 mol...
How do you calculate the mass of water that will be produced when 5.0 grams of H2 is reacted with excess O2? Calculate the mass of water produced from the reaction of 24.0 gram of H_2 and 160.0 g of O_2. What is the limiting reagent?

Instead of grams, you need to convert into mol. This requires use of the molar heat capacity formula. That means you need the specific heat of water and the molar mass of water. The molar mass of water is 18.0 g/mol. molarheatcapacity=(4.18Jmol∗K)(18.0g1mol) Multiplying that toge...
Say you need to make a solution of 1M NaCl for a reaction you are running. How would you know how much salt to weigh out and then add to a given volume of water? To do this, you need to find a way to relate the mass of a compound (salt) to the number of moles of that comp...
The mass of the solvent (water) can be calculated as:Mass of solvent=Total mass of solution−Mass of H₂SO₄=1000 g−270 g=730 g Step 5: Calculate the number of moles of H₂SO₄To find the number of moles of H₂SO₄, use its molar mass. The molar mass of H₂...
0,0202 moles of Ag+ ions have been used. Calculate the molar mass of A and B. The problem is that the molar masses I get by calculation are way too random and they dont fit for any aldehyde out there. Starting from the equation of the reaction between an aldehyde and Tollens' ...
