NaOH mass in 300.0 mL of 8.00% w/w NaOH solution

NaOH mass in 300.0 mL of 8.00% w/w NaOH solution

Calculate the mass of NaOH in 300.0 mL

of an 8.00% w/w NaOH solution.

Density is 1.09 g/mL.

---------------------------------------------------

300.0 mL × (1.09 g/mL) = 327 g 용액

327 g × (8.00/100) = 26.16 g 용질(NaOH)
