How do I do question C?! Mass to moles

1 answer:

5 0

N(CuSO₄)=135/{63.5+32.1+4*16.0}=0.846 mol

n(CuSO₄*5H₂O)=135/{63.5+32.1+4*16.0+5*(2*1.0*+16.0)}=0.541 mol

n(H₃PO₄)=135/{3*1.0+31.0+4*16.0}=1.378 mol

n(BaCl₂)=135/{137.3+2*35.5}=0.648 mol

If you double the volume of a sample of gas and then doubled the volume again without changing its pressure, how would this abso

IRINA_888 [86]

Answer:

Explanation:

Increasing Volume while maintaining constant pressure requires a proportional increase in Temperature so the gas pressure will be maintained as constant.

Consider...

V₁ = V₁ V₂ = 4V₁

T₁ = T₁ T₂ = ?

Charles Law => T ∝ V at constant P ... that is, increasing temperature generates a proportional increase in volume to maintain constant pressure.

Empirical Charles Law Relation is ...

V₁/T₁ = V₂/T₂ => T₂ = T₁(V₂/V₁) = T₁(4V₁/V₁) = 4T₁

Increasing Volume of a gas by 4 times requires a 4 times increase in absolute temperature in order to maintain constant pressure.
