Answer:
12.044 × 10²³ atoms of oxygen
Explanation:
Given data:
Number of atoms of oxygen = ?
Moles of oxygen = 2 mol
Solution:
Avogadro number:
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms of oxygen
2 mole × 6.022 × 10²³ atoms of oxygen / 1 mole
12.044 × 10²³ atoms of oxygen
PV = constant
V doubles, P will become half
New pressure = 100/2 = 50 torr
Answer:
2.70 mol of water.
Explanation:
divide the given mass by the molar mass of water. 48.5 / 18.016g = 2.70 mol water.
