To determine the number of sulfur atoms in 155 g of sulfur, you first need to calculate the number of moles of sulfur present. The molar mass of sulfur is approximately 32.06 g/mol. By dividing the given mass by the molar mass, you find that there are approximately 4.83 moles of sulfur. Since one mole of sulfur contains Avogadro's number of atoms (6.022 x 10^23), you can calculate that there are approximately 2.91 x 10^24 sulfur atoms in 155 g of sulfur.
To find the moles of sodium chloride solute in 155 grams of an 85.5% solution, first calculate the mass of sodium chloride present in the solution (mass percent x mass of solution). Then, convert the mass of sodium chloride to moles using its molar mass (58.44 g/mol). This will give you the number of moles of sodium chloride solute in the solution.
Well, Ca has an atomic mass of 40, so one mole of Ca (6.022x1023 atoms) equals 40g.To get 5kg of Ca, you would times the 40g (one mole) by 125.5kg of Ca has 125x(6.022x1023), or602200000000000000000000 atoms.
In one mole of Arsenic contains 6.02 x 10^23 atoms. This is the Avogadro's number. So in 3.5 moles of Arsenic, there would accordingly be 2.11 x 10^24 atoms.A mole of As has the Avogadro number of moles. It is equivalent to 6.022 x 10^23. Therefore, 3.5 moles of the element contains 2.11 x 10^24 atoms of Arsenic.
To convert degrees Celsius to degrees Fahrenheit, multiply by 9, divide by 5, and add 32. In this instance, 15.5 degrees Celsius is equal to 15.5 x 9 = 135/5 = 27 + 32 = 59 degrees Fahrenheit.
There are 155 Doppler radars across the US and around 122 local offices.
The atomic weight of sulfur is about 32.066. Therefore, 155 grams of sulfur contains 155/32.066 or about 4.83 gram atomic masses of sulfur to the justified number of significant digits. Each such gram atomic mass contains Avogadro's number of atoms, for a total of 4.83 X 6.022 X 1023 or 2.91 X 1024 atoms.
155 as a decimal is 155.0.
