How many molecules are in LiCi are in a 127.17 g sample?
1 mole LiCl = 42.394g = 6.022 x 1023 formula units (not molecules because it is ionic) 127.17g LiCl x 6.022 x 1023 formula units/42.394g = 1.8064 x 1024 formula units
What is the molarity of 61.7 g LiCl in 250.0 mL of solution?
Molarity = moles of solute/Liters of solution ( 250.0 ml = 0.250 liters ) Find moles. 61.7 grams LiCl (1 mole/42.391 grams) = 1.455 moles lithium chloride Molarity = 1.455 moles LiCl/0.250 liters = 5.82 M LiCl -------------------
How 2.60 moles of LiCl is dissolved in 230 mL of water What is the resulting molarity?
Molarity = moles of solute/Liters of solution ( 230 ml = 0.0230 Liters) Molarity = 2.60 moles LiCl/0.230 Liters = 11. 3 M LiCl -----------------
Does the compound LiCL have ionic or covalent bonding?
LiCl has ionic bonding. (There is no compound with a formula LiCL.)
What is the ionic formula of Na1 Cl-1?
This is the chemical formula of sodium chloride.
How many formula units of LiCl are in 127.17 g sample?

A student weighed 0.550 g of lithium chloride LiCl to use in a reaction How many moles is this?
Remember the equation # moles = mass(g) / Mr ( Relative molcular mass) The Mr of LiCl is: - 1 x Li = 1 x 7 = 7 1 x Cl = 1 x 35.5 = 35.5 7 + 35.5 = 42.5 Substituting moles(LiCl) = 0.55 g/ 42.5 = 0.0129... ~ 0.013
What does this equal LiCl plus H2SO4?
LiCl+H2SO4=LiHSO4+HCl
