What is the mass of 1.91 x 1023 C6H12O6 molecules?

57.06g

Explanation:

Molar mass of C6H12O6 = 180g/mole

1.91*10^23 molecules of C6H12O6 gives x mole of C6H12O6

6.022*10^23 molecules of C6H12O6 gives 1 mole of C6H12O6

X= 1.91*10^23 × 1 / 6.022*10^23

X = 0.317moles of C6H12O6

Y gof C6H12O6 gives 0.317 moles of C6H12O6

1 mole of C6H12O6 gives 180g

Y= 0.317 × 180

Y = 57.06g

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
