1a.P1xV1/T1=P2xV2/T2
v2=(760x70x273)/(300x76)
v2=637cm3
2a.by gas laws-
P1V1/T1=P2V2/T2
T1=27+273 =300K
P2=76cm
V2=?
T2=273K
(70×760)÷300=(76×V2)÷273
V2=637 cm³
IF IT IS USEFUL MARK AS BRAINLEST

Hello friend
___________________________________________________________
Gas equation - P₁V₁/T₁ = P₂V₂/T₂
V₁ = 760CM³ V₂ = ?
T₁ = 27CT₂ = 273K
P₁ = 70cm of hg P₂ = 76cm of hg
27C = 300K
Therefore, 760 x 70 / 300 = V₂ X 76 / 273
76 x 7 / 3 = V₂ x 76 / 273
76 x 7 x 273 / 3 = V₂ x 76
48412 = V₂ x 76
V₂ = 637cm³ Volume of STP = 637cm³
