Sodium Hydride Reacts with Excess Water to Produce Aqueous Sodium

Sodium hydride reacts with excess water to produce aqueous sodium hydroxide and hydrogen gas:

A sample of NaH weighing g will produce 982 mL of gas at 28.0 °C and 765 torr, when the hydrogen is collected over water. The vapor pressure of water at this temperature is 28 torr.
