To calculate this you need to interact a sulfate with the copper sulfate therefore when you get a copper sulfate reaction with the oxygen mask level it should create a dance dance revolution of the proxies equaling the new chemical in balance of peace birds hope this
Answer:
Number mole of calcium (Ca) = 1.4942 x 10⁻⁷ (Approx.)
Explanation:
Given:
Number of atom in (Ca) = 9 x 10¹⁶
Find:
Number mole of calcium (Ca)
Computation:
Number mole of calcium (Ca) = Number of atom in (Ca) / Avogadro's number
Number mole of calcium (Ca) = (9 x 10¹⁶) / (6.023 x 10²³)
Number mole of calcium (Ca) = 1.4942 x 10⁻⁷ (Approx.)
Number of molecules in 1 dm³ Oxygen = 2.71 x 10²²
<h3>Further explanation</h3>
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters/mol.
The mole is the number of particles contained in a substance
1 mol = 6.02.10²³
1 dm³ of oxygen = 1 L Oxygen
n=mol=0.045
No = 6.02.10²³
Hello!
Whenever you see an atomic number with an element, you know the number of protons in the nucleus of the atom, which determines the chemical of an element and its place on the periodic table.
For example, Hydrogen has only one proton, however, if you were to add say 78 more protons, you'd get gold!
