What else can I help you with?
The number of neutrons in the nucleus of a silicon atom are?
A silicon atom typically has 14 neutrons in its nucleus. This number is calculated by subtracting the atomic number (14) from the mass number (28) of silicon.
How many moles in 28.1 grams of silicon?
To determine the number of moles in 28.1 grams of silicon, you need to divide the given mass by the molar mass of silicon. The molar mass of silicon is 28.0855 g/mol. So, 28.1 grams of silicon is equal to 1 mole.
What is the mass of 1.63 x 1021 silicon atom?
To find the mass of 1.63 x 10^21 silicon atoms, you can start by calculating the molar mass of silicon (28.0855 g/mol). Then, divide the total number of atoms by Avogadro's number to find the number of moles (moles = atoms / Avogadro's number). Finally, multiply the number of moles by the molar mass to find the mass.
How do you calculate the number of moles in 2.61 grams of silicon?
For this you need the atomic mass of Si. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.2.61 grams Si / (28.1 grams) = .0963 moles Si
If an isotope of silicon has 15 neutrons what is its mass number?
The mass number of an isotope is the sum of its protons and neutrons. Since silicon has 14 protons, the isotope with 15 neutrons would have a mass number of 14 (protons) + 15 (neutrons) = 29.
What is the mass number for silicon 29?
The mass number for silicon-29 is 29. This number represents the total number of protons and neutrons in the nucleus of a silicon-29 atom.
What's the mass number for sillicon?
Silicon is a non metal element. Atomic mass of it is 28.
What element has 14 electrons and a mass number of 28?
Silicon is a non metal element. Atomic mass number of it is 28.
What is the mass number is silicon?
14
If a silicon atom contains 16 neutrons what is its mass number?
The mass number of an atom is the sum of its protons and neutrons. In this case, if a silicon atom contains 14 protons (since it is a silicon atom) and 16 neutrons, the mass number would be 14 + 16 = 30.
Silicon mass number?
28.09 g
What is the atomic mass number of silicon?
28
If an isotope of silicon has 15 neutrons what is the mass number?
The mass number of an isotope is the sum of its protons and neutrons. Silicon has an atomic number of 14, meaning it has 14 protons. If the isotope has 15 neutrons, the mass number would be 14 protons + 15 neutrons, which equals 29. Therefore, the mass number of the silicon isotope is 29.
How many grams of silicon would there be in a sample that contained 9.99 x 1025 atoms?
To determine the grams of silicon in the sample, you need to know the molar mass of silicon. Since silicon's atomic mass is approximately 28 g/mol, you can calculate the grams of silicon by dividing the number of atoms by Avogadro's number and then multiplying by silicon's molar mass. This calculation would provide you with the amount of silicon in grams in the given sample.
What is the subatomic particle os a silicon?
Silicon has 14 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a silicon isotope = Mass number - 14
What is the mass number of silicon with 14 neutrons?
The mass number of an atom is the sum of its protons and neutrons. Silicon has 14 protons making its atomic number 14. With 14 neutrons added to 14 protons, the mass number of silicon with 14 neutrons would be 28.
How many grams of silicon would there be in a sample that contained 9.99 x 1052 atoms?
To calculate the mass of silicon in the sample, you would first convert the number of atoms to moles using Avogadro's number. Then, you would calculate the mass of silicon in grams using the molar mass of silicon (28.0855 g/mol). The final mass would depend on the number of atoms in the sample.
