Explanation:
All physical quantities are generally grouped into two;
i) Vector quantities
ii) Scalar quantities
Vector quantities are those quantities that has both magnitude (size) and direction.
Scalar quantities are those quantities that has magnitude (size) and no direction.
Velocity is a vector quantity because it has direction and size.
The answer is D. Use the equation PV=nRT
P=(.567mol)(.0821)(300K)/4.5L
