Answer:
295 mL
Explanation:
Given data:
Volume needed = ?
Molarity of solution = 0.193 M
Mass of salt = 7.90 g
Solution:
Molarity = number of moles of solute / volume in L
Number of moles of salt = mass/molar mass
Number of moles of salt = 7.90 g/ 138.205 g/mol
Number of moles = 0.057 mol
Volume needed:
Molarity = number of moles / volume in L
0.193 M = 0.057 mol / volume in L
Volume in L = 0.057 mol / 0.193 M
Volume in L = 0.295 L
L into mL
0.295 L × 1000 mL/1L
295 mL
