Final answer:
To determine the mass of element q contained in 1.00 mole of each compound, calculate the percent by weight of element q in each compound.
Step-by-step explanation:
To determine the mass of element q contained in 1.00 mole of each compound, we need to calculate the percent by weight of element q in each compound. This can be done by dividing the mass of element q in 1.00 mole of the compound by the molar mass of the compound and multiplying by 100%. The percentages add up to 100%.
