GIVEN: w=25gm, MM(H2O)=18gm, M=2 molar, V=10L TO FIND: Molar Mass of Substance FORMULAE: 1) Molarity = (moles/Vol. (in L)) [M = n/V] 2) moles=(Weight/Molar Weight) [n = w/MM] SOLUTION: Moles of substance = 25/MM Molarity = [(25/MM)/10] 2 x 10 = 25/MM 20 = 25/MM MM = 25/20 MM = 5/4 MM = 1.25gm CONCLUSION: The molar mass of this substance is 1.25gm (Is it correct?)

Mam one question
25g of a substance is mixed with water and form 2 molar and 10L solution than calculate the molar mass of this substance?
Aree bhai kisi se ho please solve me
GIVEN: w=25gm, MM(H2O)=18gm, M=2 molar, V=10L
TO FIND: Molar Mass of Substance
FORMULAE:
1) Molarity = (moles/Vol. (in L)) [M = n/V]
2) moles=(Weight/Molar Weight) [n = w/MM]
SOLUTION:
Moles of substance = 25/MM
Molarity = [(25/MM)/10]
2 x 10 = 25/MM
20 = 25/MM
MM = 25/20
MM = 5/4
MM = 1.25gm
CONCLUSION: The molar mass of this substance is 1.25gm
(Is it correct?)
