The formula mass of sodium sulfide, Na2S, is 2(23.0)+32.1=78.1
Amount of sodium sulfide = 73.5/78.1 = 0.941mol
1 mol of H2 is necessary.

Definition of density: Density = mass / volume; solving for density: volume = mass / density. Density of silver is about 10.5 grams/cm3.
The estimated value of the density is 1,87 g/cm3. The atomic mass of the most stable isotope, 223Fr, is 223,019 735 9(26).
The mass of 0,005 moles of paradichlorobenzene is ,735 g.
735 g of Ca3(PO4)2 are obtained.
735 hours.
735 centimeters is 7.35 meters.
735 ÷ 5 = 147
It goes into 735, 61.25 times.
There are 100 centimetres in one metre. Therefore, 735 metres is equal to 735 x 100 = 73500 centimetres.
One HP is 735 W, so 600/735=0.8 HP
