Answer :
M(NaCl)=M(Na)+M(Cl)
=23+35
=58 g/mol
n=m/M n=c.v ρ=m/v
m=2g v=30ml=0.03l
molarity of sodium chloride is:
n=m/M
=2/58
=3.4.10(-2)mol
the percent mass/volume is:
ρ=2/0.03
=2/3 10^2 g/l
=23+35
=58 g/mol
n=m/M n=c.v ρ=m/v
m=2g v=30ml=0.03l
molarity of sodium chloride is:
n=m/M
=2/58
=3.4.10(-2)mol
the percent mass/volume is:
ρ=2/0.03
=2/3 10^2 g/l
