What are the options? but the constants I know for sure are 22.4L the molar mass of an ion . I just need to know the options
M = n / V
M = 0.5 / 0.05
M = 10 mol/L-1
Hope this helps!
Answer:
Mass = 0.6 g
Explanation:
Given data:
Moles of NaOH = 0.015 mol
Mass of NaOH = ?
Solution:
Number of moles = mass/ molar mass
by rearranging this formula,
Mass = number of moles × molar mass
Molar mass of NaOH is 40 g/mol
by putting values,
Mass = 0.015 mol × 40 g/mol
Mass = 0.6 g
