The formula for an ionic compound shows the simplest whole-number ratio of the large numbers of ions in a crystal of the compound. A molecular formula is a whole-number multiple of the empirical formula. The molar mass of any compound is equal to the molar mass of the empirical formula times a whole number…

Ratio and Proportion . I. Ratios are everywhere – can you give examples? A. Def. Ratio – an ordered pair of numbers written a:b, with b not equal to zero. 1. Allows us to compare the relative sizes of 2 quantities. B. Ratios are like, but not like fractions. 1. They can compare part-to-whole or whole …

Use the percent composition to convert to mass. Then use molar mass to convert to number of moles. Finally, determine whole-number ratios based on the number of moles of each element per 100 grams of compound. Calculate. Step 2. Solve for the unknown. One hundred grams of compound has 67.6 g Hg, 10.8 g S, and 21.6 g O.

Initially, students may fill ratio tables with columns or rows of the multiplication table by skip counting, using only whole number entries, and placing these entries in numerical order. Gradually, students should consider entries in ratio tables beyond those they find by skip counting, including larger entries and fraction or decimal entries.
