Question

if the density of methanol is 0.793 kg L*-1 what is its volume needed for making 2.5 L of its 0.25 M solution?



please solve this question urgent ​

Answer 1

Ans0.25⋅mol⋅L−1×2.5⋅L=0.625⋅mol with respect to methanol . And thus a mass of 0.625⋅mol×32.04⋅g⋅mol−1=20.0⋅g with respect to methanol. And so we need a volume of 20.0⋅g793⋅g⋅L−1=0.0253⋅L≡25.25⋅mL wer:

Answer 2

Ans

0.25⋅mol⋅L−1×2.5⋅L=0.625⋅mol with respect to methanol . And thus a mass of 0.625⋅mol×32.04⋅g⋅mol−1=20.0⋅g with respect to methanol. And so we need a volume of 20.0⋅g793⋅g⋅L−1=0.0253⋅L≡25.25⋅mL wer:
