It must be made of matter because anything and everything is made up of atoms. The other three options are made of atoms but they are also matter.
The correct answer is A. Oxygen became used to carry out many processes and to drive a few anaerobic processes.
1 mole of particles = 6.02*10²³
8.59 *10²³atoms*(1 mol/6.02*10²³ atoms) = (8.59/6.02) mol
M(Cl)=35.5 g/mol
(8.59/6.02) mol*35.5 g/mol=50.7 g
Dear friend,
Because the water remains water throughout this process, it is not undergoing any chemical change. There is no new substance or element added but only a change of form.
Answer:
a) ρ = 3.735 Kg/m³
b) γ = 36.603 N/m³
c) Vw = 2.68 E-4 g/m³
Explanation:
- PV = RTn .....ideal gas law
a) ρ = m/V
∴ Mw air = 28.966 g/mol......from literature
⇒ P = RTn / V
∴ n = m / Mw
⇒ P = mRT / Mw.V = m/V * R.T/Mw
∴ P = 50 psi = 344738 Pa
∴ R = 8.3144 Pa.m³/mol.K
∴ T = 120°F = 48.889 °C = 321.889 K
⇒ ρ = (( 344738 Pa ) * ( 28.996 g/mol )) / (( 8.3144 Pa.m³/mol.K) * ( 321.889K ))
⇒ ρ = 3734.996 g/m³ * ( Kg / 1000g ) = 3.735 Kg/m³
specific weight:
- γ = w / V = m.g / V = ρ *g
∴ ρ = 3.735 Kg/m³
∴ g = 9.8 m/s²
⇒ γ = 36.603 N/m³
c) specific volume
⇒ Vw = (( 8.3144 Pa.m³/ mol.K ) * ( 321.889 K )) / ( 344738 Pa )* ( 28.966 g/mol)
⇒ Vw = 2.68 E-4 g/m³
