1. Using the conversion formula to convert from Molarity to Normality, convert a 2 M CaCl 2 solution to its Normality value. (2pts) 2. Convert a \( 5.0 \mathrm{mEq} / \mathrm{L} \) Calcium standard to \( \mathrm{mg} / \mathrm{dL} \) units.(2pts) 3. What is the molarity of a \( 35 \% \mathrm{w} / \mathrm{v} \) solution of \( \mathrm{NAOH} ?(2 \mathrm{pts}) \) 4. \( 45 \mathrm{~mL} \) of a \( 50 \% \mathrm{v} / \mathrm{v} \) ETOH solution is needed. In the stock room is a bottle of \( 75 \% \mathrm{v} / \mathrm{v} \) ETOH. How much of the stock should be used?(2pts) 5. \( 10.40 \mathrm{~mL} \) of a \( 35 \% \mathrm{v} / \mathrm{v} \) acetic acid solution is needed. In the stock room is a bottle of \( 50 \% \mathrm{v} / \mathrm{v} \) acetic acid. How much water should be used as the diluent?(2pts)
