We need moles of Ca(OH)_2

  • Molarity=Moles/Volume in L
  • 0.025=Moles/1.5
  • Moles=1.5(0.025)
  • Moles=0.0375mol

Molar mass of Ca(OH)_2=74g/mol

Now

  • Mass=Molar mass×Moles
  • Mass=0.0375×74
  • Mass=2.77g

Option C

FromTheMoon [43]
I choose question 1, so molarity is the concentration of a soulution expressed as the number of moles of solute by the litress of soulution. to get molarity you divide the moles of soulute by the litress of solution. soo 1 calculate the number of moles of solute present. 2 Calculate the number of litress solution present. 3. divide the number of moles of solute by the number of litress of solution
soo 1 mol of NaOH has a mass of 40.00 g, so moles of NaOH= 26.7. 1 mole divided 40.00 = 0.375. litress of solution = 650 g. im not sure why its a g i usally do it Ls so i guess its the way your teacher wants you to do it so do you know how to do that. so molarity = moles of solute and litress solution. sorry this probably didnt help i just wanted to add something that might help. im still working on this stuff myself hope this helps.
