Answer: The volume for 0.850 mol of  from a
 from a  solution is 1700 mL.
 solution is 1700 mL.
The volume of 30.0 g of LiOH from a 2.70 M LiOH solution is 464 mL.
Explanation:
Molarity is the number of moles of solute present in a liter of solution.
- As given moles of  are 0.850 mol and molarity of are 0.850 mol and molarity of solution is 0.5 M. Hence, its volume is calculated as follows. solution is 0.5 M. Hence, its volume is calculated as follows.

Therefore, the volume for 0.850 mol of  from a
 from a  solution is 1700 mL.
 solution is 1700 mL.
- As given mass of LiOH are 30.0 g from a 2.70 M LiOH (molar mass = 23.95 g/mol) solution. Hence, its number of moles are calculated as follows.

So, volume for LiOH solution is calculated as follows.

Therefore, volume of 30.0 g of LiOH from a 2.70 M LiOH solution is 464 mL.
