Well, the density of a Element remains the same no matter what state, the density of liquid Niobium would be the same as solid I think, therefore, would be:
8.57 g·cm−3
My question to you though, is why would you need to know? It is kinda of a high temperature to be liquid...
Melting Temps:
2750 K, 2477 °C, 4491 °F
To determine the number of moles in nickel acetate, you need to know the mass of nickel acetate. Once you know the mass, you can use the formula: moles = mass / molar mass. The molar mass of nickel acetate is 176.7 g/mol.
The mass number is the sum of the number of protons and neutrons. Every atom of nickel has 28 protons, but not every atom has the same number of neutrons. The mass number will depend on the isotope.See link below for information on nickel and its isotopes as well as the related question which will explain how to find these numbers in various examples.
9.3*10^15 atoms nickel = ? grams take the number of atoms, divide by one mole and then times by the molar mass of nickel 9.3*10^15atoms /6.02*10^23 atom/mol * 58.69 g/mol =9.1*10^-7 grams
First, calculate the volume of one nickel pyramid paper weight using the formula for the volume of a pyramid: (1/3) * base area * height. Then, multiply this volume by the density of nickel (8.9g/cm^3) to find the mass of one nickel pyramid paper weight. Finally, multiply this mass by 12 to find the total mass of a dozen such paper weights.
The conventional standard atomic weight of the hydrogen atom is 1,008 amu.
The atomic mass of nickel is 58.69. Nickel is a metal element.
The mass of a U.S. nickel is 5.0 grams.
Nickel is a meta element. Atomic mass of it is 59.
Cobalt has an atomic mass of 58.933195(5) while nickel has an atomic mass of 58.6934(4). Nickel has the lower atomic mass.
