Question

Two elements, R and Q, combine to form two binary compounds. In the first compound, 14.0 g of R combines with 3.00 g of Q. In the second compound, 7.00 g of R combines with 4.50 g of Q. Show that these data are in accord with the law of multiple proportions. If the formula of the second compound is RQ, what is the formula of the first compound?

Step 1

For the first compound: \[ \text{Mass ratio of R to Q} = \frac{14.0 \, \text{g of R}}{3.00 \, \text{g of Q}} = \frac{14.0}{3.00} = 4.67 \] For the second compound: \[ \text{Mass ratio of R to Q} = \frac{7.00 \, \text{g of R}}{4.50 \, \text{g of Q}} = Show more…
