2️⃣ kilogram
3️⃣ newton
4️⃣ dalton​

Answer 1

Answer:

4) Dalton (√)

The dalton or unified atomic mass unit (symbols: Da or u) is a unit of mass widely used in physics and chemistry. It is defined as 1/12 of the mass of an .

Answer 2

The modern unit of determining the mass of an atom is Dalton.

• The atomic mass of any substance is an extremely small amount of mass which cannot be effectively measured by our regular units of maas, like - kilograms.
• That's why, there's a seperate unit for this which is known as Atomic Mass Unit, or AMU. This Atomic Mass Unit is also known as the Dalton unit. (1 AMU = 1/12th mass of an atom of Carbon-12)
• Rest of the given units are used for other purposes.
