@mathslover

Answer 3

\[mean\] \[250cm ^{3}\]

Answer 4

yeah

Answer 5

hmn wait...

Answer 6

ok

Answer 7

ok so the unit of density is = ?

Answer 8

just tell me this... so that i can proceed @KingAditya

Answer 9

kg m^{-3}

Answer 10

kg/m^3

Answer 11

right...

Answer 12

unit of volume = cm^3 ( CGS )

Answer 13

yeah

Answer 14

Ok so now... what does M denote ? Molar...?

Answer 15

mole

Answer 16

m waiting

Answer 17

m answering....

plz wait until i give you correct answer...

Answer 19

ok @mayankdevnani

Answer 20

can any one help me

Answer 21

@ParthKohli

Answer 22

250cm^3 = mL

Answer 23

0.250L = 250mL

\[Molarity = \frac{MolesOfSolute}{LitersOfSolution}\]

Answer 24

0.500M = x mole/0.250L
0.500M*0.250L = 0.125mol

then use the following formula to solve for Grams:

\[Moles = \frac{Grams}{MolecularMass}\]

Answer 25

\[\large{0.125=\frac{grams}{58.44}}\]

just multiply 0.125 * 58.44

Answer 26

yup yup

Answer 27

though good work @Australopithecus ....
