In what net direction will water diffuse (by osmosis) when the following solutions are brought into contact with each other on different sides of a semipermeable membrane? Left Right
0.4 M fructose 0.2 M glucose + 0.3 M fructose
0.3 M NaCl 0.4 M glucose

a. No net flow
b. left to right
c. right to left

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"

c

explanation:

i believe the answer is 5,000
