In summary, the formula for calculating molar mass is M = m/n, where M is the molar mass, m is the mass of the compound in grams, and n is the number of moles of the compound. To calculate the molar mass of Sr(NO3)2, you will need to determine the molar mass of each element in the compound and add them together. Molar mass is typically expressed in grams per mole (g/mol). Calculating molar mass is important in chemistry for understanding and predicting chemical reactions and accurately measuring and comparing substances. Yes, the molar mass of a compound can be different from its molecular mass due to the consideration of the number of moles.

Hi
my question is
What is the molar mas of: Sr(NO3)2
1 mol Sr ((87.62 g Sr)/(1 mol Sr)) = 87.62 g
2 mol N ((14.007 g N)/(1 mol N)) = 28.014 g

6 mol O ((15.999 g O)/(1 mol o)) = 95.994 g

The molar mas is (87.62 g + 28.014 g + 95.994 g) = 211.628 g

Correct.
 

1. What is the formula for calculating molar mass?

The formula for calculating molar mass is M = m/n, where M is the molar mass, m is the mass of the compound in grams, and n is the number of moles of the compound.

2. How do I calculate the molar mass of Sr(NO3)2?

To calculate the molar mass of Sr(NO3)2, you will need to determine the molar mass of each element in the compound and multiply it by the number of atoms of that element in the compound. Then, add all of these values together to get the final molar mass. For Sr(NO3)2, the molar mass would be calculated as follows: M(Sr) + 2(M(N)) + 6(M(O)) = 87.6 g/mol + 2(14.0 g/mol) + 6(16.0 g/mol) = 211.6 g/mol.

3. What units are used for molar mass?

Molar mass is typically expressed in grams per mole (g/mol).

4. Why is calculating molar mass important in chemistry?

Calculating molar mass is important in chemistry because it allows us to determine the mass of a substance in relation to the number of moles of that substance. This is essential for understanding and predicting chemical reactions and for accurately measuring and comparing substances.

5. Can the molar mass of a compound be different from its molecular mass?

Yes, the molar mass of a compound can be different from its molecular mass. Molar mass takes into account the number of moles of a compound, while molecular mass only considers the mass of the individual atoms in the compound. Therefore, a compound with the same molecular formula but different numbers of moles will have different molar masses.
