In each formula unit of NaCl there is one Na+ ion.
Therefore, amount of sodium ions
= amount of NaCl
= 4.25mol
Let us find moles first. Molarity = moles of solute/Liters of solution ( 750 ml = 0.750 Liters ) 0.375 M Na2SO4 = moles Na2SO4/0.750 Liters = 0.28125 moles Na2SO4 =================== 0.28125 moles Na2SO4 (142.05 grams/1 mole Na2SO4) = 39.95 grams Na2SO4 needed ---------------------------------------you do significant figures!
425 degrees Fahrenheit is equivalent to 218.3 degrees Celsius.
Gas mark 7 is approximately 425°Fahrenheit.
A size D oxygen cylinder typically contains 425 liters of oxygen. At a flow rate of 4 liters per minute, the cylinder would last approximately 106 minutes.
Carpet can catch fire at temperatures around 600-800°F (315-425°C). It is important to keep sources of heat, such as candles or heaters, away from carpet to prevent potential ignition.
The answer is 1.35 moles.425 g of UF4 would be 1.35 moles.
425 g calcium (Ca) is equal to 10,604 moles.
To calculate the number of moles of calcium in 425 g, you need to divide the given mass by the molar mass of calcium. The molar mass of calcium is approximately 40.08 g/mol. moles = 425 g / 40.08 g/mol ≈ 10.61 moles of calcium.
To calculate the mass of an atom, 1amu = 1.66*10^-24 and sodium has a mass of 22.99amu. Therefore, 425 sodium atom would be 425*(22.99*(1.66*10^-24))=1.6219445~-20. With the sig fig, the final answer is: 1.62*10^-20g
Its 425
425 ÷ 25 = 17
There are: 425*60 = 25,500 seconds
