Answer:
Volume of AgNO₃ = 4.9 ml (Approx)
Explanation:
Given:
Total solution = 75 ml
Volume of AgNO₃ = 6.5%
Find:
Volume of AgNO₃
Computation:
Volume of AgNO₃ = Total solution x Volume of AgNO₃
Volume of AgNO₃ = 75 x 6.5%
Volume of AgNO₃ = 4.875
Volume of AgNO₃ = 4.9 ml (Approx)
In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects. ... Electrical forces are extremely sensitive to distance.
Density of a substance is given by dividing its mass with volume.
The volume of the block is 3.5 cm× 2.0 cm ×1.5 cm = 10.5 cm³
thus density = 34.56 g/ 10.5 cm³
= 3.291 g/cm³
The sodium-potassium pump of cell function is to take 2 potassium atoms into cells and dump the 3 sodium outside cells. The pump is also needed ATP as energy to make it work. That is why the pump sometimes referred as Na3/K2 ATPase pump.
The pump cannot do these things separately. That means if there are much potassium outside cells but there is no sodium, the pump will catch and keep the potassium then wait until they find sodium inside cells. If there is no sodium inside cells, the pump will not work even if there is much potassium outside.
