How many atoms of sulfur are present in 155 g of sulfur?
93,341,000,000,000,000,000,000,000 or 933.41 x 1023 atoms of arsenic. You just take Avogadro's number (6.022 x 1023) and multiply 6.022 by the number of moles (155) and then multiply the product by 1023.
How many moles of sodium chloride solute are in 155 grams of an 85.5 percent by mass solution?
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.
What is 155 degrees Celsius in Fahrenheit?
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.
How many atoms are in 125 grams of Calcium?
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.
How many atoms are there in 3.5 moles of arsenic?
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.
What element has the atomic mass of 254 and 155 neutrons?
The element with an atomic mass of 254 and 155 neutrons is californium (Cf). Its atomic number is 99, meaning it has 99 protons. To find the number of protons, you can subtract the number of neutrons from the atomic mass: 254 - 155 = 99. Therefore, californium has 99 protons and 155 neutrons.
How many neutrons are there in an element having a mass number of 155 and an atomic number of 63?
The number of neutrons in the nucleus of an atom is always the difference between the mass number of the atom and the atomic number of the atom. Therefore, in this instance, there are (155 - 63) or 92 neutrons in the atom.
Would an atom with 60 protons and a mass number of 155 be stable?
An atom with 60 protons would be the element neodymium (Nd), which has atomic number 60. A mass number of 155 suggests it has 95 neutrons (155 - 60). Neodymium-155 is a stable isotope, so the atom would be stable.
Is the symbol for an atom with 107 protons and 155 Neutrons 107 155 BH?
262107BHJust imagine the 262 is directly above the 107, the upper number is the atomic mass number which is the sum of the number of protons and neutrons while the lower number is the atomic number which is just the number of protons.
How many neutrons would there be if An atom of gadolinium has an atomic number of 64 and a mass number of 155?
91
What is the element mendelevium atomic structure?
The atom of the isotope Md-256 has 101 protons, 101 electrons and 155 neutrons.
How does atomic radius vary down the group iv elements?
Atomic radius in group 4:- titanium=140 pm- zirconium=155 pm- hafnium=155 pm
How many atoms of sulfer are present in 155 grams of sulfer?
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.
What is my mass in kilograms if I weigh 155 pounds?
To convert pounds to kilograms, divide the weight in pounds by 2.205. So, if you weigh 155 pounds, your mass is approximately 70.3 kilograms.
What is the density if a car has a volume of 125mL and a mass of 155g?
Density = mass/volume = 155/125 = 1.24 g/cm3.
Can you show work finding density with a mass of 155 pounds and volume of 4.2 ft cubed?
To find density, use the formula Density = Mass/Volume. Convert mass of 155 pounds to kg by dividing by 2.205 (1 kg = 2.205 pounds). Therefore, 155 pounds = 70.31 kg. Next, divide the mass by the volume (70.31 kg / 4.2 ft^3) to find the density. The density is approximately 16.74 kg/ft^3.
