Below is a simple set of weights obtained while immersing potato slices in various sugаr solutions over 60 minutes. Time OM sucrose 0.4M sucrose 0.6M sucrose (min) 0.8 M sucrose 1.0M sucrose
(min)
0 4.36 g 4.59 g 4.7g 4.5 g 5.0 g
30 4.5 g 4.3 g 4.4 g 4.1 g 4.6 g
60 4.68 4.28 4.0 g 3.7 g 4.08
For each solution, calculate the rate of weight change over this 60-minute period.
Using the osmosis data in the question above, determine the percent weight change for each sucrose solution.
0.0M sucrose = %
0.4M sucrose = %
0.6M sucrose = %
0.8M sucrose = %
1.0M sucrose = %

Explanation:

The rate of weight change can be determined by using the formula:

weight change = weight at the final time - weight at the initial time.

Molarity                     Weight change

0.0M sucrose  →        (4.68 - 4.36)  =  0.32  g/min

0.4 M sucrose →         (4.28 - 4.59) =  - 0.31  g/min

0.6 M sucrose →         (4.0 - 4.7)      =  - 0.7   g/min

0.8 M sucrose →         (3.7 - 4.5)      = - 0.8    g/min

1.0 M sucrose  →         (4.08 - 5.0)   = - 0.92  g/min

Percent weight change =

Now;

Molarity                     Weight change

0.0M sucrose  →             =   6.8 %

0.4 M sucrose →              = 8.4 %

0.6 M sucrose →               = 14.8 %

0.8 M sucrose →               = 17 %

1.0 M sucrose  →                = 18.4%

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.

idk and i also need to know where are those bio brainy acts lol
