Explanation:
it's one mole because the atomic mass is treated as molar mass and the atomic mass of strontium is 87.62 grams/mol
Answer:
Explanation:
no, as it can also be used to describe a gas- a fluid includes liquids, gases and plasms
Answer:
16.499 × 10∧ 21 atoms
Explanation:
Given data:
mass of P2O5= 0.560 g
number of atoms= ?
first of all we will calculate the molar mass of P2O5:
P = 2×31 g/mol = 62 g/mol
O = 5× 16 = 80 g/mol
molar mass of P2O5 = 142 g/mol
Noe we will find the moles of 0.560 g P2O5:
moles = mass / molar mass
moles = 0.560 g/ 142 g/mol
moles = 0.0039 mol
now we will find the atoms present in 0.0039 moles:
0.0039 × 6.02 × 10∧ 23 molecules
2.357 × 10∧ 21 molecules
P2O5 consist of 7 atoms:
2.357 × 10∧ 21 × 7 = 16.499 × 10∧ 21 atoms
Sulfur hexafluoride or SF6 is an inorganic, greenhouse gas. It is non-flammable, odorless, and colorless, and is an excellent insulator. It is a hypervalent octahedral molecule that has been an interesting topic of conversation among chemistry enthusiasts.
