Boyle's Law
G: V1= 130 mL
P1= 0.97 atm P2= 1 atm (standard pressure)
U: V2=?
F: V2 = V1 P1/P2
S: V2 = (130 mL) (0.97 atm) / 1 atm
Answer : V2 = 126.1 mL volume of the gas occupy @ STP
A sand castle was changed by the ocean waves would be slowly taken away by the waves and would just become a smooth mound of sand. If someone stomped on it then it would still have the same amount of sand as before but in a different shape.

The number of C atoms in 0.524 moles of C is 3.15 atoms.
The number of molecules in 9.87 moles is 59.43 molecules.
The moles of Fe in 1.40 x atoms of Fe is 0.23 x
The moles of in 2.30x molecules of is 3.81.
<h3>What are moles?</h3>
A mole is defined as 6.02214076 × of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
A. The number of C atoms in 0.524 mole of C:
6.02214076 × x 0.524 mole
3.155601758 atoms =3.155 atoms
B. The number of molecules in 9.87 moles of :
6.02214076 × x 9.87
59.4385293 molecules= 59.43 molecules
C. The moles of Fe in 1.40 x atoms of Fe:
1.40 x ÷ 6.02214076 ×
0.2324754694 x moles.
0.23 x moles.
D. The moles of in 2.30x molecules of :
2.30x ÷ 6.02214076 ×
3.819239854 moles=3.81 moles
