When a person pushes off a wall with 15N of force,how much force does the wall push back

aivan3 [116]

Newton's third law of motion states that for every action force, there is an equal and opposite reaction force so that means that the wall is pushing you with the same amount of force that you put on it.

Answer:

Answer: 760 uM

Explanation:

the addition of solvent to a solution in a such away that the volume of the solution increases and the concentration decreases is a process know as dilution

The concentration and the volume of the dilute and concentrated solution are given below as follows

$C_{1}V_{1}$ $= C_{f}V_{f}$

Concentrated solution Dilute solution

Given that M1 = 97.0uM

V1 = 47.0 mL

V2 = 6.0 mL

M2 = ?

Therefore M1V1 = M2V2

M2 = M1V1/V2

M2 = (97*47)/6

M2 = 760 uM

Answer: 760 uM

. Calculate the number of moles in 56g of H20

svetoff [14.1K]

<h3>Answer:</h3>

3.11 moles

<h3>Explanation:</h3>

We are given 56 g of water (H₂O)

Required to calculate the number of moles of water.

The relationship between moles, mass and molar mass is given by;
Moles = Mass ÷ molar mass

in this case;

Mass of water = 56 g
Molar mass of water = 18.02 g/mol

Therefore;

Moles of water = 56 g ÷ 18.02 g/mol

= 3.11 moles

Therefore, moles of water in 56 g will be 3.11 moles
