72.98 g/mol
78.22 g/mol
88.24 g/mol
97.99 g/mol

97.99

Explanation:

Molar mass of H = 1.0079 g/mol; P = 30.974 g/mol; O = 15.999 g/mol

Using that just add the numbers up :)

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
