Elevation grade (or slope) is the steepness, or degree of inclination, of a certain area of land.It can simply be the steepness between two specific points in a given area, the average of an area's gradual change in steepness, or an erratic variation in the elevation of the ground. We usually measure the ground's elevation as its altitude above sea level.
Suppose you need to prepare 2 liter of a 1 M solution of potassium nitrate (KNO 3). The molecular weight of KNO 3 is 101.1 g/mol. How much potassium nitrate should you weigh out? First, rearrange the molarity equation to solve for the mass of solute m: m = M×MW×V = 1 M × 101.1 g/mol × 2 L = 202.2 g
