The three sub particles of an atom are protons, electrons and neutrons.
<u>Explanation:</u>
Neutrons, electrons, and protons are the three sub atomic particles of an atom. Electrons are negatively charged, protons are the positively charged and neutrons are neutral. Electrons are having 9.1×
kg, protons and neutrons are having a mass of 1.67×
kg.
As protons possess positive charges, so the atomic number of protons will be 1 , similarly, the atomic number of electrons will be -1 and neutron is zero. So, electrons, protons and neutrons combine together to form the atom.
As the electrons present with negative charge and protons with positive charge, along with this the protons number are equal to electrons number, this confirm the neutral nature of atoms.
Answer:0.025576559594663 mole.
Explanation:
Answer:
2.A baby grasshoper is a nymph.
Explanation:
Answer : The correct option is, The concentration of the acid.
Explanation :
Molarity : Molarity is defined as the moles of solute present in one liter of the solution. Or it is defined as the concentration of solute present in one liter of solution.
The unit of molarity is, (M) i.e, mole/liter. It is also known as molar concentration.
Molarity of 0.01 M means, 0.01 concentration of the acid present in the solution.
Therefore, the 0.01 M refer to the concentration of the acid.
Answer: Molarity of the prepared solution is 
Explanation:
Molarity is defined as the number of moles of solute dissolved per liter of the solution.
where,
n= moles of solute
= volume of solution in ml = 500 ml
moles of solute =
Now put all the given values in the formula of molarity, we get
Thus molarity of the prepared solution is
