Hcl 38%
WebJun 15, 2024 · You are given % HCl and you want to make a molar (6 M) solution of HCl. We will assume that the 32-38% HCl is mass/volume. So, for example, 32% HCl (m/v) = 32 g HCl / 100 ml. To make 100 ml of 6 M HCl, that is equal to 0.1 L of 6 M. 0.1 L x 6 mol / L = 0.6 mol HCl needed. molar mass HCl = 36.5 g / mol. 0.6 mol HCl x 36.5 g / mol = 21.9 g … WebApr 26, 2024 · The amount of hydrochloric acid (HCL) administered is based upon base excess (milliequivalent/liter), with an equivalent amount being administered. One report recommends the following formula (Wagner et al, 1980g): HCL (mEq) = Weight (kilogram) x 0.3 X base excess (mEq/liter).
