All mol triangles
WebA triangle consists of various parts. It has 3 angles, 3 sides, and 3 vertices. Observe the triangle PQR given below which shows the sides, the vertices and the interior angles of a triangle. In the triangle given above: The three angles are, ∠PQR, ∠QRP, and ∠RPQ. The three sides are side PQ, side QR, and side RP. The three vertices are P, Q, and R WebThe gram formula mass of a substance is known as the mass of one mole. The mass, number of moles, concentration or volume of a substance can be calculated easily if you learn two formula triangles.
