I prefer to replace ppm with units six orders of magnitude apart so I can use unit cancellation, µg/g for mass/mass, µL/L for volume/volume, mg/L for mass/volume, etc. Your calculations are correct, but you might find this a useful way to look at it. 1000 ppm MgSO4 is 1000 mg/L.

Hill Formula: MgO₄S CAS #: 7487-88-9 EC Number: 231-298-2 Chemical Formula: MgSO₄ Molar Mass: 120.37 g/mol. 106067.
Step 3: Divide each individual element’s molar mass by the total molar mass of the compound. Multiply by 100 to make a percent. Molar mass of Na x 100 = _____ Total molar mass of NaCl Molar mass of Cl x 100 = _____ Total molar mass of NaCl 11.

Equivalent mass for H3PO4 is 98/3 = 32.6. NaOH, potassium hydroxide. The gram-molecular mass is 40. The number of hydroxide ions (OH-) is 1. Equivalent mass for NaOH is 40/1 = 40. Once the equivalent mass of an acid or base is determined, you can then calculate the amount of grams needed per volume of water for N. The formula to calculate this is:

Apr 08, 2017 · Sulfuric acid's molar mass is "98.08 g/mol". Step one: Find the atomic masses in each atom -- units: "g/mol" Hydrogen: 1.01 Sulfur: 32.06 Oxygen: 16 Step two: Find how many of those atoms are of the formula: Hydrogen: 2 atoms Sulfur: 1 atom Oxygen: 4 atoms Step three: Add all the atomic masses together. (Note, if there are more than one of a particular atom, you must multiply it by how many of ... mass of the magnesium strip used. By dividing the volume by the number of moles we obtain the molar volume at the temperature and pressure at which the experiment is performed. In order to find the molar volume at STP, we apply the Ideal Gas Law: P V = n R T where P = the pressure of the gas V = the volume of the gas
