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
To find the number of moles of hydrogen gas, we first need to calculate the number of moles of chlorine gas using the ideal gas law formula (PV = nRT). Once we have the moles of chlorine gas, we can determine the moles of hydrogen gas needed for the reaction. In this case, the stoichiometry of the reaction states that 1 mole of chlorine gas reacts with 1 mole of hydrogen gas, so the required moles of hydrogen gas will be equal to the moles of chlorine gas.
The height of the mercury column in the tube represents the balance between the atmospheric pressure pushing down and the pressure exerted by the column of mercury pushing up. With a height of 735 mm, the atmospheric pressure can be calculated as 735 mm Hg or 735 torr.
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 density of silver is 10.49 grams per cubic centimeter. To find the volume needed to contain 21 grams of silver, divide the mass by the density: 21 grams / 10.49 g/cm^3 ≈ 2 cubic centimeters.
The mass of 0,005 moles of paradichlorobenzene is ,735 g.
735 g of Ca3(PO4)2 are obtained.
735 hours.
735 ÷ 5 = 147
735 centimeters is 7.35 meters.
It goes into 735, 61.25 times.
To determine how many times 2 goes into 735, you can divide 735 by 2. The result is 367.5, which means 2 goes into 735 a total of 367 times with a remainder. Thus, 2 fits into 735 a whole number of 367 times.
There are 100 centimetres in one metre. Therefore, 735 metres is equal to 735 x 100 = 73500 centimetres.
To find out how many times 21 goes into 735, you would divide 735 by 21. The result is 35, meaning that 21 goes into 735 a total of 35 times. This calculation is done by dividing the dividend (735) by the divisor (21) to get the quotient (35).
One HP is 735 W, so 600/735=0.8 HP
