6.84g Of Sucrose Is Dissolved In 200g Of Water. The Molality Of Solutions Is, A. 0.2m, B. 0.3m, C. 0

6.84g of sucrose is dissolved in 200g of water. the molality of solutions is

A. 0.2M
B. 0.3M
C. 0.1M
D. 0.02M

✏️CHEMISTRY

===============================

SOLUTION :

\small\sf\ {Molecular  \: weight  \: of  \: sucrose \:  (C_{12}H_{12}O_{11}})=\red3\red4\red2

\small\sf{1000g \: of  \: water = 5×6.84=\red3\red4\red.\red2}

\small\sf{molality = \frac{32.2}{342} = \small\boxed{\green{\sf{0.1M}}} }

===============================

ANSWER :

  • Therefore , among the choices the answer is probably 0.1M (C).

===============================

Hope this helps :)
