Question

what is M solution

Answer 1

Molar solution amount of solute in 1 litre of solvent

Answer 2

thanks for reply. U mean that moecular wegiht of a solute in 1 L solvant?

Answer 3

yaaa for example NaOH molecular weight is 40
40 gram in 1000 ml (1L) of water gives 1M NaOH solution

Answer 4

oh thanks dear. A BIG thanks for you.

Answer 5

can i ask one thing

Answer 6

yes please

Answer 7

if 40 gram in 1000 ml (1L) of water gives 1M NaOH solution
then 4 gram in 1000 ml (1L) of water gives X NaOH solution
X= ???

Answer 8

wait i have to calculate

Answer 9

100g in 1000 ml

Answer 10

NOOO

Answer 11

4 g in 1000ml

Answer 12

could u pls tell me quickly

Answer 20

did u leave me?

Answer 21

if 40g/1000ml = 1M
then 4g/1000 ml = \(\frac{4*1}{40}=X\)

Answer 22

0.1

Answer 23

0.1M NaOH solution yes

Answer 24

tx for help dear

Answer 25

can I ask one more question pls.

Answer 26

what does it m,ean by 0.25 M NaCl

Answer 27

and how can I calculate it

Answer 28

It means the same, just the molarity.
0.25M means 0.25 mol NaCl per Liter solution

The molar mass of NaCl is 58.44 grams/mol
so 1 mol = 58.44 gram
0.25 mol = 0.25*58.44 = 14.61 gram

So there is 14.61 gram NaCl in 1 Liter solution (14.61 g/L)
