WebThe formula weight of hydrogen gas is 2.01594, that of oxygen gas 31.9998, and that of water 18.01534. Our chemical equation is numerically equivalent to 2×2.01594+31.9998=2×18.01534 or 4.03188+31.9998=36.03068 if the formula weight of each reactant is substituted for the formula of that reactant. From this equation we … WebWeight average also called weighted mean is helpful to make a decision when there are many factors to consider and evaluate. Each of the factors is assigned some weights based on their level of importance, and then the weighted average is calculated using a mathematical formula.

WebA weight (w) n is attached to each of the values (x) n. The general formula to find the weighted mean is given as, Weighted mean = Σ (w) n (x̄) n /Σ (w) n where, x̄ = the mean value of the set of given data. w = corresponding weight for each observation. The simple steps used to calculate the weight mean through the formula is: WebFeb 25, 2024 · To find molarity you will need to convert this number of grams into moles by using the molar mass of NaCl: To find the molarity, you can divide the number of moles by the volume of the solute (in liters): This means that a 21% w/v solution of NaCl is the same as a 3.6 solution of NaCl. In this way, you can convert between concentration ... WebA weight (w) n is attached to each of the values (x) n.
