How many atoms are there in 0.25 mole of oxygen?
so, 0.25 moles of oxygen there is 6.023/4×10^23 molecules.
How many moles of oxygen atoms is this?
One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.
How many moles of Ca3 PO4 2 will contain 0.04 moles of oxygen atoms?
Answer: 1 mole of Ca3(PO4)2 has 8 moles of oxygen, so for 0.25 mole of atomic oxygen you need (0.25/8 =) 0.03125 mole of the compound.
How many moles of caco3 will contain 0.12 mole of oxygen atoms?
contain 1.5 moles of oxygen atoms.
How many particles are present in 0.25 mole of an element?
1 mole of an element contains 6.022*10²³ particles. Hence, 0.25 moles of an element will contain 6.022*10²³*0.25=1.5055*10²³ particles.
How many atoms are present in a 0.25 mole sample of carbon?
Of moles = No. of atoms/Avogadro’s No. => No. of atoms = 1.5055 x 10^23 atoms of Carbon.
How many moles of magnesium phosphate contains?
Hint:Magnesium phosphate has 3 moles of magnesium, two moles of phosphorus and eight moles of oxygen atom in its chemical formula. Because there are three magnesium atoms, two phosphorus atoms and eight oxygen atoms in magnesium phosphate molecules.
How many atoms are in 4 moles oxygen?
Oxygen gas (O2) is made up of 2 atoms of oxygen. Since oxygen has an atomic mass of 16 g/mole, the molar mass of oxygen gas (O2) is 2 x 16 g/mole = 32 g/mole. Since 1 mole of oxygen is equivalent to 32 g, 4 moles of oxygen gas would be equivalent to 4 moles x 32 g/mole = 128 g.
How many atoms of O are there in 4875 milligrams of Ca3 PO4 2?
Question: How many atoms of O are there in 4875 milligrams of Ca3(PO4)2? Answer in scientific notation: x 10 atoms of.
How many moles of c3po 42 will contain 0.4 mole of oxygen atoms?
Answer: Explanation: 1 mole of Ca3(PO4)2 has 8 moles of oxygen, so for 0.25 mole of atomic oxygen you need (0.25/8 =) 0.03125 mole of the compound.
How many phosphate ions are in mg3 PO4 2?
There are two phosphate ions in a molecule of magnesium phosphate.
