The volume of a sample of gas is 200 mL at 275 K and 0.891 atm. What will the new volume of the gas be at 770C and 98.5 kPa? HELP!!?

P₁ = 0.891 × 101.3 kPa, V₁ = 200 mL, T₁ = 275 K
P₂ = 98.5 kPa, V₂ = ? mL, T₂ = (770 + 273) K = 1043 K
For a fixed amount of gas :
P₁V₁/T₁ = P₂V₂/T₂
V₂ = V₁ × (P₁/P₂) × (T₂/T₁)
New volume, V₂ = (200 mL) × (0.891 × 101.3 / 98.5) × (1043/275) = 695 mL
P₂ = 98.5 kPa, V₂ = ? mL, T₂ = (770 + 273) K = 1043 K
For a fixed amount of gas :
P₁V₁/T₁ = P₂V₂/T₂
V₂ = V₁ × (P₁/P₂) × (T₂/T₁)
New volume, V₂ = (200 mL) × (0.891 × 101.3 / 98.5) × (1043/275) = 695 mL
