write a formula of unit mass plzzzz fasstt
Answers
Answer:
Newton's second law of motion states that force equals mass times acceleration: F = ma. If you know the net force on the object, and it's acceleration, you can rearrange this formula to find the mass: m = F / a. Force is measured in N (newton), which you can also write as (kg * m)/ s 2. Acceleration is measured in m/s 2.

Answer:
The mass of the formula unit of a substance is the sum of the atomic masses of all atoms in an ionic compound's formula unit.
Explanation:
The key to calculating the formula mass of an ionic compound is to correctly count each atom in the formula and multiply the atomic masses of its atoms accordingly. Use the atomic masses (rounded to two decimal places) to determine the formula mass for each ionic compound. a. The formula mass of FeCl3 is 162.2 amu.
