I mole of copper hydroxide is 98g (64 + 16 + 1 + 16 + 1)
So 68g is 68/98 moles
= 0.694g
I have used 64 for the ram of copper. Your list might use a slightly different value, so substitute that.

∙ 7y agomolar mass of copper(II) hydroxide, Cu(OH)2 is 97.6 g/mole. Thus...
68 g x 1 mol/97.6 g = 0.696 = 0.70 moles (2 significant figures).

What is 16 grams of oxygen how many moles?
16 grams of oxygen how many moles is 0,5 moles.
How many moles are in 272g?
It depends on what the subtance is, i.e. whether there is 272g of copper, sodium chloride, lithium hydroxide or what. The way to calculate the amount of a subtance in moles is to divide the mass of the substance (in grams) by the atomic mass, molecular mass or formula mass of the element, molecular compound or ionic compound respectively, as the case may be.

How many grams of sodium hydroxide (NaOH) are there in 0.150 mol?
0,15 moles NaOH contain 6 g.
How many grams does 2.2 moles of NaOH weigh?
Need total molar mass sodium hydroxide which you can easily get from your periodic table. 2.2 moles NaOH (39.998 grams/1 mole NaOH) = 88 grams in mass ==============
How many grams of sodium hydroxide are there in 0.150 mol?
The molecular weight of sodium hydroxide is 40. Therefore 0.150 moles would be 40 x 0.15 = 6g.
How many electrons in 2.9 grams of copper?
i havent got an elements table in front of me but here is how you do it: figure out how many moles is 2.9 grams of copper by using molecular wieght, then simply multiply so: No of moles* No of atoms in one mole* number of electrons in one atom of copper (which is the same as the No of protons...)
If you have 60 grams of sodium hydroxide NaOH (FW 40 gramsmole) how many moles of sodium hydroxide would you have?
60 g NaOH x 1 mole NaOH/40 g NaOH = 1.5 moles NaOH
You were hired by a laboratory to recycle 6 moles of silver ions You were given 150 g of copper How many grams of silver can you recover Is this enough copper to recycle 6 moles of silver ions?
No you need more copper
How many grams of solute are required to make a 918 mL solution of sodium hydroxide with a concentration of 0.4922 M?
Molarity = moles of solute/Liters of solution ( 918 ml = 0.918 liters )rearranged algebraically,moles of solute = Liters of solution * Molaritymoles of NaOH = (0.918 l)(0.4922 M)= 0.45184 moles NaOH=======================so,0.45184 moles NaOH (39.998 grams/1 mole NaOH)= 18.1 grams sodium hydroxide needed============================
