Formula for Molarity is given as,
Molarity = moles / Volume of Solution in L ----(1)
Also,
Moles = mass / M.mass
Putting value of mole in eq. 1,
Molarity = (mass / M.mass) / Vol
Solving for mass,
Mass = Molarity × M.mass × Vol
Putting Values,
Mass = 0.15 mol/L × 40 g/mol × 0.5 L
Mass = 3 g
Result:
Weight 3 g of NaOH, add it to a 500 ml volumetric flask, and add distilled water to the point of 500 ml. The resulting solution will be 0.15 M.
The double and triple bond present in the molecule determines the shape of the molecule because the strength of the bond may tend to allow the bending in the molecule thus, revealing a different orientation. An example of this is sulfur dioxide (SO₂) which is a trigonal planar.
Answer:
The nucleus makes up a tiny proportion of the space occupied by an atom, while the electrons make up the rest. According to quantum electrodynamics, the space is filled by an electron field around the nucleus which neutralizes its charge and fills the space defining the atom size.
Answer:
hmm
Explanation:
The overall charge of an atom is zero. Atoms are made up of positively charged particles called protons and negatively charged particles called electrons as well as non-charged particles called neutrons.

An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral.

I hope this helped!
Answer:
Its mass and volume
Explanation:
Matter can be defined or described as anything that takes up space, and it is composed of miniscule particles called atoms. It must display the two properties of mass and volume.
