We calculate the number of protons using the formula for calculating the charge:
q = N * qp, where q is the total charge of protons (q = 1.5 C), N is the required number of protons, qp is the value of the proton charge (numerically equal to the charge of an electron qp = 1.6 * 10 ^ -19 C).
N = q / qp.
Let’s perform the calculation:
n = 1.5 / (1.6 * 10 ^ -19) = 9.375 * 10 ^ 18 protons.
Answer: The total charge of 1.5 C is 9.375 * 10 ^ 18 protons.
