Question

The mass of proton is 1.67 X 10-27 kg. how many protons would make 1kg

Answer 1

Answer:

1 mole of protons mass x avogad7 number gives no of protons for 1 kg

Answer 2

Answer:

Mass of proton (m) = 1.67×10^(-27) kg. N = 6x10^(23) (approx.) Exact mass of proton gives N = 6.022 x 10^(23).

Explanation:

How many protons would make 1kg ?

1027 / 1.67 = 0.60 * 1027 .

The mass of a proton is 1.67 ×10−27kg,

so the number of protons required to make up

1kg is the reciprocal of this

(1027) / 1.67 = 0.60 * 1027 .

Proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron.

Number of protons = Total mass / Mass of each electron = ${{10}^{-3}} / 1.67 x ${{10 }^{-27}}$ = 5.99 x ${{10}^{23)

The mass of a proton is 1.67×10−27 kg, so the number of protons required to make up 1kg is the reciprocal of this - namely (10^27)/1.67 = 0.60*10^27
