A student uses water displacement to find the volume of a sample of gold. If the initial volume of the water is 25.5 mL, and the volume after placing the gold in the water is 30.5 mL. What is the volume of the gold?

Phosphorous acid, h3po3(aq) , is a diprotic oxyacid that is an important compound in industry and agriculture. p k a1 p k a2 1.30 6.70 calculate the ph for each of the points in the titration of 50.0 ml of 1.5 m h3po3(aq) 1.5 m h 3 po 3 ( aq ) with 1.5 m koh(aq). 1.5 m koh ( aq ) .
