Put the steps below in the order they are performed in the lab experiment by numbering them 1-7.
Use a Bunsen burner to heat and dry the hydrate, repeating until the mass no longer decreases.
Measure the final masses of the crucible, cover, and anhydrous salt.
Compute differences in masses to find the reactants and products.
Measure initial masses of the crucible and cover, with and without the hydrate.
Use the numbers of moles to compute the mole ratio.
Use stoichiometry to convert these masses to moles.
Use the mole ratio to write the hydrate's formula.

Determine the percent sulfuric acid by mass of a 1.61 m aqueous solution of h2so4. %

For a family dinner, jose’s mom baked a loaf of bread. during the meal, his grandmother commented, “this bread is so dense! ” what do you think his grandmother meant by the word dense? you have some ideas regarding density already, but this experiment will enrich your understanding of the relationship between mass, volume and the density of objects. when making measurements in this experiment we will be using si units, the international system of units. the purpose of using si units is to have the ability to communicate and compare data results with other experiments without having to make conversions. measurement symbol si unit length m meter mass kg kilogram volume l liters density kg/l kilograms per liter any calculations that are performed during this experiment will ultimately be reported in scientific notation. recall that scientific notation is extremely important when we have data that is extremely small or large. scientists rely on a standard form of communication to quickly make hypotheses and judgements based on data. what is the density of block a? a0kg/l what is the density of block b? a1kg/l what is the density of block c? a2kg/l what is the density of block d? a3kg/l what is the density of block e? a4kg/l which block is the densest? a5
