- what does (98% wt/wt) mean? The question I'm being asked is "what is the mass of 10.57 mL of acetic acid (98% wt/wt)?"arrow_forwardscaling up Solutions Sometimes we know the concentration of a solute but we need to make a larger volume of the solution. Example: An IV saline solution is based on 0.9% NaCI = 0.9g/100mL (dL). To make 1L of the same concentration (0.9%), how many grams of NaCl would we need? Hint: first convert mL or dL to L. Next, to get from our original volume of 0.1 L to our desired volume of 1L, we need to multiply by a factor of 10. If we want to keep the concentration of this solution the same (0.9%) we will also need to multiply the amount of solute by the same factor of 10. Molar Ratios and Chemical Equations The concept of the mole is useful in chemical reactions. Molecules react in molar ratios which are expressed in equations. Neutralization of an Acid Example: HCI + NaOH → NaCI + H2O This equation says that 1 mole of acid is neutralized by 1 mole of base to produce 1 mole of salt and 1 mole of water. Since a mole is the MW in grams, then you can calculate how much base you need to to…arrow_forwardA patient order requires 1.8 L of a 0.4% benzalkonium chloride antiseptic.
