Calculation problem
Posted: Mon Nov 01, 2021 3:52 am
Hi people,
I'm trying to solve the following problems:
Problem 1:
1) How many grams HCl with mass fraction ω=36,5 % will fully dissolve 6 g Mg?
2) What's the mass fraction ω of MgCl2 in the formed solution?
For 1) I've calculated that 18,25 g HCl will fully react 6 g Mg - is this correct?
For 2) will the MgCl2 solution have ω=36,5 %? - is this correct?
Problem 2:
How many grams HCl with ω=30 % are needed to neutralise 500 ml NaOH solution with density ρ=1,2 g/ml and ω(NaOH)=10 %?
My calculations give 182,5 g HCl needed to neutralise the given amount of NaOH - is this correct?
Thanks for verifying and helping in advance.
Greetings,
Ned
