Q

% concentration to Mg/ml

A

2 % solution means= 2 gm in 100 ml
so it means= 2x1000 mg / 100 ml= 20 mg/ml

in this case % concentration is based on g/ml

a 2% solution is: (1ml x 2%)/100 = 0,02g/ml
0,02g/ml x 1000 = 20mg/ml (becouse 1g = 1000mg)

124
Q

% concentration to Mg/ml

A

2 % solution means= 2 gm in 100 ml
so it means= 2x1000 mg / 100 ml= 20 mg/ml

in this case % concentration is based on g/ml

a 2% solution is: (1ml x 2%)/100 = 0,02g/ml
0,02g/ml x 1000 = 20mg/ml (becouse 1g = 1000mg)
