What is the ratio of molecules in 1 mole?

1 mole of any compound is the Avogadro’s number, 6.023×1023 . And, 1 mole of HNO3 = 6.023×1023 molecules. Now, both compounds have the same number of molecules. The ratio of molecules between both the compounds is 1:1 .

Which is the correct formula to calculate the mass ratio of ammonia NH3 )?

Since there are 3 Hydrogen atoms present, the formula mass of H is 1.0 × 3 = 3.0 g/mol. Therefore, by adding them up, the formula mass of ammonia is: [14.0 g/mol + 3.0 g/mol] = 17.0 g/mol.

How is Class 9 mass ratio calculated?

1. Step 2: Determine the Mass of Each Individual Element Present. In this step, you multiply the number of atoms in one molecule of the compound by the molar masses you collected in Step 1.
2. Step 3: Determine the Molar Mass of the Compound.
3. Step 4: Divide the Mass of Each Element Present by the Molar Mass.

How do you calculate formula masses?

Explanation: To calculate formula mass, multiply the subscript of each element in the formula by the element’s atomic weight (relative atomic mass) found on the periodic table. The unit for formula mass is either u or Da (Daltons). The amu has been replaced with u, even though it is still commonly used.
