Question

Calculate the mass of a proton (in kg) using the charge-to-mass ratio given below and its known charge. (The charge of a proton is 1.602 ✕ 10−19 C and the charge-to-mass ratio of a proton is 9.579 ✕ 107 C/kg. Round your answer to at least four significant figures.)

Answer 1

Answer:

$1.672\times 10^{-27}kg$

Explanation:

Given:

Charge-to-mass ration of a proton, $\frac{q_p}{m_p}=9.579 \times 10^7 C/kg$

charge of a proton, $q_p=1.602\times 10^{-19} C$

mass of the proton can be calculated as follows:

$m_p= \frac{q_p}{q_p/m_p} = \frac{1.602\times 10^{-19}C}{9.579 \times 10^7 C/kg} = 1.672\times 10^{-27}kg$

Thus, the mass of a proton is $1.672\times 10^{-27}kg$
