NUMERICALS IN HARDNESS Calculate the hardness of water containing 146 mg/l of magnesium bicarbonate. Hardness = 100 ppm 100 ml of standard hard water contains 1 mg of CaCO3 per ml. 20 ml Concentration in parts per million (ppm): The parts of a component (A) per million parts (10 6) of the solution. Concentration in parts per billion (ppb): The parts of a component (A) per billion parts (10 9) of the solution. Molarity: It is the number of gram equivalents of solute present in one litre of the solution and it is denoted by M. Free six sigma calculator which combines multiple tools into one: DPMO calculator, DPM calculator, RTY calculator, sigma level calculator.

Parts Per Million (ppm) Concentration Calculations. Question 1. 150 mL of an aqueous sodium chloride solution contains 0.0045 g NaCl. Calculate the concentration of NaCl in parts per million (ppm). Write an equation representing the ppm concentration: ppm = mass solute (mg) ÷ volume solution (L) Extract the data from the question:

Neet 2020 prep/ Jee mains 2020 prep. EX: A water treatment operator must super chlorinate a 650,000-gallon tank at 50 ppm. How much chlorine must the operator add? 50 × .65 × 8.34 = 271 pounds * You must divide 650,000 by one million to get .65 to solve the equation. Round to the nearest tenth or hundredth place to get the most accurate answer.

Precision. Computers use binary numbers, so if we make our numerical measurement more precise by using smaller quantising levels, there must be more of them, and a binary word comprising more bits is required. The foam in acid gas scrubbing solutions created during an acid gas scrubbing process is reduced or eliminated by the addition of certain polyoxyethylene polyoxypropylene block cpolymers as defoaming agents. In this class, Chapter 1 of Chemistry for Class 11th will be continued with topics MOLALITY, MOLE FRACTION and PPM (Mostly Numericals). Learners preparing for CBSE and NEET and are in Class 11th, 12th and droppers will benefit from this session. We will start by the NCERT text, Reading in between the lines.
