  1. 16% w/v means 16 g ethanol in 100 mL solution. So add 5*16 = 80 g ethanol, place in a 500 mL volumetric flask, and make to the mark with distilled water.

    Find the number of mg Na2co3 FW = 106g/mol required to prepare 500ml of 9.2ppm NA solution. ppm = mg/L 9.2mg/1000ml x= 0.0092 x 500ml = 4.6mg x 23 = 106mg The right answer 10.6mg NA weight = 23 Who helps me to solve it for me.

    You are a workstudy for the chemistry department. Your supervisor has just asked you to prepare 500mL of 3M HCl for tomorrow's undergraduate experiment. In the stockroom explorer, you will find a cabinet called "Stock Solutions".
