Which formula can be used to calculate the molar mass of water (H2O)?

the molar Mass of water (H2O) can be calculated by adding the molar masses of the individual elements present.

Molar Mass of H2O = (2x1) + 16 = 2 + 16 = 18g/mol

Explanation:

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
