How many different isotopes of erbium are there?
The formula is Atomic Mass (rounded to the nearest whole number) minus the Atomic Number. This works because Protons and Neutrons have virtually the same mass, and electrons virtually none. As well as the Atomic Number being equal to the amount of Protons. Essentially: Protons + Neutrons - Protons = Neutrons. Basic Prealgebra. So to find the amount of Neutrons in Erbium: Erbium's Atomic Mass rounded (167) - Erbium's Atomic Number (68) = approx. 99 Neutrons
What is the mass number of Dy?
166
What is the molar mass of KI?
The gram formula mass for KI or potassium iodide is 166.0027 grams per mole. You find this mass by multiplying the atomic masses of potassium and iodine by the number of atoms given for each in the formula, and then adding these two results.
How many meters are in 166 kilometers?
166 kilometers=166,000 meters
How many grains equal 166 ppm equal?
There are 166 parts per million (ppm) of a substance in a solution. The conversion of ppm to grains per gallon depends on the specific substance being measured, as different substances have different conversion factors. For instance, for calcium carbonate, 166 ppm is equal to approximately 9.7 grains per gallon.

What is the total number of isotopes in platinum?
Platinum has six naturally occurring isotopes. They range from 190 to 196 in atomic mass. There are 31 synthetic isotopes in platinum that range from 166 to 202 in atomic mass.
What is atomic mass of C12H22O11?
Multiply the atomic mass of C (Carbon), which is 12, by its charge (12). multiply the atomic mass of H (hydrogen), which is 1, by its charge (22). multiply the atomic mass of O (Oxygen), which is 16, by its charge (11). Add them together as shown below 12(12) + 22(1) + 11(16) = ? 144 + 22 + 171 = ? 166 + 171= ? Atomic mass = 337
What is the mass number of Dy?
166
What is the percentage of iodine in potassium iodide?
The percentage of iodine in potassium iodide can be calculated using the formula: (molar mass of iodine / molar mass of potassium iodide) x 100. The molar mass of iodine is approximately 126.9 g/mol, and the molar mass of potassium iodide is approximately 166 g/mol. Therefore, the percentage of iodine in potassium iodide is (126.9 / 166) x 100 = 76.5%.
How many protons neutrons and electrons are in erbium?
Protons-68 Electrons-68 Neutrons-About 99
What is the molar mass of KI?
The gram formula mass for KI or potassium iodide is 166.0027 grams per mole. You find this mass by multiplying the atomic masses of potassium and iodine by the number of atoms given for each in the formula, and then adding these two results.
What is 49.5 percent of 166?
49.5% of 166= 49.5% * 166= 0.495 * 166= 82.17
How many moles of potassium iodide are there in 50 grams?
For this you need the atomic (molecular) mass of KCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. KCl= 74.6 grams50.0 grams KCl / (74.6 grams) = .670 moles KCl
How many kilograms is 166 pounds?
It is equal to 75.29 kilograms approximately. Kilogram is the metric unit and pound is the imperial unit for mass. 1 Kilogram is 2.204 pounds. So we multiply pound by 0.4535 to get the equivalent kilograms.
