Therefore, we need to use mole-mass calculations in combination with mole ratios to solve several different types of mass-based stoichiometry problems. In this type of problem, the mass of one substance is given, usually in grams. From this, you are to determine the amount in moles of another substance that will either react with or be produced from the given substance. The mass of the given substance is converted into moles by use of the molar mass of that substance from the periodic table.
Then, the moles of the given substance are converted into moles of the unknown by using the mole ratio from the balanced chemical equation. Tin metal reacts with hydrogen fluoride to produce tin II fluoride and hydrogen gas, according to the following balanced equation. Step 1: List the known quantities and plan the problem. This will be done in a single two-step calculation. The answer has three significant figures because the given mass has three significant figures.
In this type of problem, the amount of one substance is given in moles. From this, you are to determine the mass of another substance that will either react with or be produced from the given substance. The moles of the given substance are first converted into moles of the unknown by using the mole ratio from the balanced chemical equation. What scientific concept do you need to know in order to solve this problem? Our tutors have indicated that to solve this problem you will need to apply the Mole Concept concept.
