step 1:
Calculate the number of moles of solute by multiplying max of the solute and the inverse of molar may of solute.
step 2:
Calculate the volume of the solution by multiplying number of moles of solute and the inverse of molarity
mass of Ca(NO3)2= 5.79
molar mass of Co (NO3)2 = 164.09 glmol
number of moles of solute [Ca(NO3)2] = [tex]\frac{mass}{molar mass\\}[/tex]
[tex]\frac{5.7g}{164.09glmol}[/tex] = 0.0347mol
hence, the no. of moles of solute is 0.0347 moles
molarity of solution= 4.00M
[tex]\frac{0.0347mol}{4.00M}[/tex]
= 0.00867L
=8.67ml
what is molar mass?
- In other terms, molar mass is the total mass of all the atoms in a substance that makes up one mole.
- Molar mass is also known as "mass per mole." It is measured in gram-per-mole units.
- For elements or molecules, molar mass is shown. The molar mass is simply the element's mass represented in atomic mass units in the case of single elements or individual atoms.
- To put it another way, an atom's atomic mass and molar mass are precisely identical. Molar mass may be used to determine a particle's identification because it is equivalent to atomic mass for individual atoms.
