4. compare and contrast molar mass and molecular mass
Answer:
Moreover, the main difference between both is that "molar mass gives the mass of a mole of a particular substance". Whereas "molecular weight is the mass of a molecule of a particular substance". While the definition and units are different for molar mass and molecular weight, the value is the same

Answer:
1. Add all the molar masses of what composes sodium hydroxide (NaOH)
Na x 1 = 22.989 g/mol
O x 1 = 15.999 g/mol
H x 1 = 1.008 g/mol
Total molar mass of sodium hydroxide is 39.996 g/mol
2. First you look up molar masses in a data book, periodic table, etc.
Write down the molar mass of each element. In this case:
Magnesium: 24.305 grams per mole
Chlorine: 35.45 grams per mole
Then write the chemical formula of magnesium chloride down. I assume you know how to determine chemical formulas of simple compounds.
MgCl2
To determine the molar mass multiply the molar mass of each element in the compound by the number of atoms of each element in the compound.
(24.305gmol^-1 x 1) + (35.45gmol^-1 x 2)
= 95.205 grams per mole.

Answer:
The molar mass of a substance is the mass in grams of 1 mole of the substance. As shown in this video, we can obtain a substance's molar mass by summing the molar masses of its component atoms. We can then use the calculated molar mass to convert between mass and number of moles of the substance.18. 1. What is the average atomic mass of Ca? What is the molar mass of Ca? 2.

How do you find the molar mass of CA?Solution:
Solution:Formula =Ca(NO3)2.
Molar mass Ca=40.08g/mol.
Molar mass N=14.01g/mol.
Molar mass O=16.00g/mol.
How do I find molar mass?The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol). The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms.
However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.

27. II. Task: Determine the molar mass Water (H₂O) Elements No. of Atoms Atomic Mass Total Mass Molar Mass (MM)=
Explanation:
The molar mass of water (H2O) can be determined by adding up the atomic masses of each element present in the compound.
Water is composed of two hydrogen atoms (H) and one oxygen atom (O).
The atomic mass of hydrogen is 1.008 amu (atomic mass units).
The atomic mass of oxygen is 16.00 amu.
Therefore, the total mass of water is:
(2 x 1.008) + 16.00 = 18.016 amu
And the molar mass (MM) is equal to the total mass in amu, so the molar mass of water is 18.016 g/mol.
