What is the mass of one mole of Ca(OH)2? A. 58.06 g/mol

B. 114.18 g/mol

C. 74.10 g/mol

D. 57.09 g/mol

74.10g/mol

Explanation:

The mass of one mole of Ca(OH)₂ is the molar mass of the compound.

To solve this problem, we add the atomic masses of the species in the compound;

 Atomic mass of Ca = 40.078g/mol

                             O = 15.9994g/mol

                            H = 1.0079g/mol

So;

  Molar mass  =  40.078 + 2(15.9994 +1.0079 )  = 74.10g/mol

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
