Answer:
Explanation:
Concentration is molarity.
Molarity = number of moles of solute / volume of solvent in L
number of moles is not given so, we are going to use this formula
Moles = Mass / molar mass
Moles = 0.15g / 159.609g/mol
Moles = 0.00094 moles
now substitute in the first formula:
Molarity = number of moles of solute / volume of solvent in L
Molarity = 0.042M
Moles = 0.00094 moles
0.042 = 0.00094 / Volume in L
Volume = 0.022 L
L to mls we have to multiply by 1000
So 0.022 L = 22.38 mls
final answer: 22.38 mls
