How many particles of oxygen are in 2 moles of O2 gas?
According to the concept, 1 mole contains 6.023 ×10^23 particles. So, 2moles of O2 contains 2× 6.023×10^23 molecule= 12.046 ×10^23 molecule .
What is the volume of 2 moles of oxygen gas at STP?
so 2mol O2 occupies 44.8L of volume at STP.
What is the mole formula?
Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).
What is K mole?
39.10 grams is the molar mass of one mole of K.
How many moles of oxygen atoms O are present in 2.0 moles of oxygen gas O2?
How many moles of oxygen atoms are present in 2.0 g of oxygen O2? 1 mole of O2= 2 moles of O. So Moles of oxygen = 2 x 0.0625=0.13 moles of O.
How many atoms are present in 2 moles?
If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms.
