The density of titanium metal is 4.51 g/cm3 at 25 °C. what mass of titanium displaces 125.0 ml of water at 25 °C. The density of benzene at 15 °C is 0.8787 g/mL. calculate the mass of 0.1500 L of benzene at this temperture.
The rate law for the reaction, 2NO(g) + O2(g) -- 2NO2(g), is found to be: rate of reaction=k[NO]2[O2]2 (PLEASE note that the 2's after the concentrations are powers, so we have NO to the power of 2 and O2 to the power of
