The melting range is the span of temperature from the point at which the crystals first begin to liquefy to the point at which the entire sample is liquid.

Explanation:

For all of the questions, do the following calculation

$\frac{isotope \: \times abundance}{100} + \frac{isotope \: \times abundance}{100} ...$

As an example, I'll do question 1

$\frac{204 \times 1.480}{100} + \frac{206 \times 23.6}{100} + \frac{207 \times 22.6}{100} + \frac{208 \times 52.3}{100} = 207.20$
