milliequivalents number of positive ions in salt solution usually K Ca or Mg solutions 1 mEq=molecular weight/charge of ion Ex-- KCl has ion charge of 1+. mol wt of K is 17 mol wt of Cl is 39. 56/1=56g of KCl is dissolved in 1L of solution

scales pharmacy torsion balance---very accurate small measurement. 6mg to 120gm. sample goes left plate using tweezers right plate gets weights, pharmacy scale------electronic, add your sample graduated cylinder---use smallest cylinder necessary. plastic cylinder look at flat top. for glass look at meniscus. syringe---look at black right that touches fluid.

temperatures F to C= (f-32)/1.8 100F=(100-32)=68/1.8= 37.7c C to F=(1.8 x c) +32 100c to F= 1.8x 100= 180+32= 212f
