Molarity NaOH = 0.250M Volume NaOH = 32.20mL Volume H 2SO 4 = 26.60mL Unknown First determine the moles of NaOH in the reaction. From the mole ratio, calculate the moles of H 2SO 4 that reacted. Finally, divide the moles of H 2SO 4 by its volume to get the molarity. Step 2: Solve.
WebAug 20, 2024 · By definition, it is the number of gas particles per million air particles, 1 ppm = 1/1000000 = 0.0001% = 0.001‰. Sometimes, however, the gas concentration is expressed as the mass concentration in milligrams per cubic meter (mg/m3). For example, permissible exposure limits (PEL or OSHA PEL) are expressed both in ppm and in mg/m³.
