Question

what is formula unit mass ?​

Answer 1

Answer:

The formula mass of a substance is the sum of the average atomic masses of each atom represented in the chemical formula and is expressed in atomic mass units. The formula mass of a covalent compound is also called the molecular mass. ... The mass in grams of 1 mole of substance is its molar mass.

The formula unit mass of a substance is the sum of the atomic masses of all the atoms in the formula unit of an ionic compound. = 2Na + 1C + 3O = (2 × 23) + (1 × 12) +( 3 × 16) = 46 + 12 + 48 = 106 u.

◇How to find formula unit

mass?

--》There are 6.022×1023 in 1 mole of anything, including formula units. You need to determine the number of moles in 0.335 g CaO . Once you know the number of moles of CaO , you can determine the number of formula units by multiplying the number of moles by 6.022×1023
