Answer:
it is not correct I have an answer for ''why''
Explanation:
You need to balance it
s= 2
0=2
S+30•2 --------> SO•3
2 2 2 2
S +3O•2-------->SO•2......MULTIPLY
2 4 2 4......LCM IS 4
2 1 2 1....DIVIDE BY 4
SO NOW WE GOT THE BALANCE NO. WE CAN PUT IT IN THE EQUATIONS.
2S+3O•2 -----> 2SO•3
now you can check the both sides its balances the correct answer is this
Molality is a measure of concentration that relates the moles of solute to the kilograms of solvent, it is described by the following equation:
We are given the molality(2.50m) and kilograms of solvent(0.500kg), so we solve for moles of solute from the equation:
To make a 2.50molal NaOH solution would be needed 1.25moles of solute
Answer: 1.25 moles
Answer:
1000 gram
