I’m pretty sure it’s true
Answer:
Q.1
Given-
Volume of solution-1 L
Molarity of solution -6M
to find gms of AgNO3-?
Molarity = number of moles of solute/volume of solution in litre
number of moles of solute = 6×1= 6moles
one moles of AgNO3 weighs 169.87 g
so mass of 6 moles of AgNO3 = 169.87×6=1019.22
so you need 1019.22 g of AgNO3 to make 1.0 L of a 6.0 M solution

Answer:
A. An identification of the atoms in a molecule
Explanation:
The chemical formula of a compound is a representation which shows all the elements therein and the mole relationship between them expressed as subscripts.
Therefore, a chemical formula allows us to identify atoms that are within a molecule.
A molecule is a covalent compound that has discrete or separate units.
For example;
HCl represents 1 mole of hydrogen chloride molecules consisting of 1 mole of hydrogen atoms and 1 mole of chlorine atoms.
