Answer:
Molarity is a unit for expressing the concentration of a solution
Explanation:
Molarity is used to express the concentration of a solution. Also known as molar concentration, molarity is the number of moles of solute (the material dissolved) per liter of solution. It measures the concentration of a solution. The molarity of a solution is calculated by taking the moles of solute and dividing by the liters of solution. Hence, Molarity (M) indicates the number of moles of solute per liter of solution (moles/Liter) and is one of the most common units used to measure the concentration of a solution.
Molarity is commonly expressed as molar. Molar also refers to the unit of concentration called molarity, which is equal to the number of moles per liter of a solution. In chemistry, the term most often refers to molar concentration of a solute in a solution. Molar concentration unit also implies the units mol/L or M.
These nuclei with different numbers of neurons are called isotopes
Answer:
0 kgm/s
Explanation:
The momentum of Bob while resting at the river is 0 kgm/s.
This is because the momentum of any object at rest is 0.
Momentum is the quantity of motion a body contains. It is mathematically expressed as;
Momentum = m x v
m is the mass
v is the velocity
So at rest, the velocity of a body is 0m/s and therefore, the momentum is O
