Explanation of the solution to the problem: the mass fraction of the impurity in the sample is found by the formula:
w = m (approx.) / m (sample) * 100%, where w is the mass fraction of the impurity, m (approx.) is the mass of the impurity in the sample, m (sample) is the mass of the sample. Substituting the data in the condition of the value problem, we get: w = m (approx.) / M (sample) * 100% = 10/100 * 100% = 10%.
