97% of the naturally occurring Calcium is isotope Ca-40, so massnumber 40.
Other isotopes have massnumber 42 to 48
No, calcium (Ca) has a mass number of 40, while argon (Ar) has a mass number of 40 as well.
Calcium: ~Atomic weight: 40.078 ~Atomic #: 20 ~Density: 1.55 ~Alkali Earth Metal
The mass number of an isotope is the sum of its protons and neutrons. Calcium (Ca) has an atomic number of 20, meaning it has 20 protons. If the isotope has 24 neutrons, the mass number would be 20 protons + 24 neutrons = 44. Therefore, the mass number of this calcium isotope is 44.
To find the number of moles in 16.5g of calcium, first determine the molar mass of calcium (Ca), which is approximately 40.08g/mol. Then, divide the given mass by the molar mass to get the number of moles. In this case, 16.5g ÷ 40.08g/mol ≈ 0.411 moles of calcium.
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Calcium's atomic mass is 40.08 grams.

For this you need the atomic mass of Ca. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. Ca= 40.1 grams.761 moles Ca × (40.1 grams) = 30.5 grams Ca
The atomic symbol for an isotope of calcium will be the regular symbol for calcium, Ca. The number of protons will differ from standard calcium. This is written below the mass number Ca.
To determine the number of moles of calcium atoms in 45.8 g of Ca, first find the molar mass of calcium (Ca) from the periodic table (40.08 g/mol). Then, divide the given mass by the molar mass of Ca to get the number of moles. In this case, 45.8 g of Ca is equal to 1.14 moles of Ca atoms.
To find the number of moles, you need to divide the given mass of calcium by its molar mass. The molar mass of calcium (Ca) is approximately 40.08 g/mol. Number of moles = 77.4 g / 40.08 g/mol ≈ 1.93 moles.
For Ca isotope 40 it is 20 neutrons and 20 protons, but there are 5 other naturally occurring (>2%) Ca-isotopes with mass numbers ranging from 42 - 48. Remember: p + n = mass number, so n = m - p
The element that has a mass number of and two valence electrons is an isotope of calcium.
To find the number of moles in 16.5g of calcium, first determine the molar mass of calcium (Ca), which is approximately 40.08g/mol. Then, divide the given mass by the molar mass to get the number of moles. In this case, 16.5g ÷ 40.08g/mol ≈ 0.411 moles of calcium.
For this you need the atomic mass of Ca. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.40.0 grams Ca / (40.08 grams) = .998 moles Ca
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Calcium's atomic mass is 40.08 grams.
