A student is ready to determine the density of their 10% solution. He has run out of clean beakers and decides to reuse the beaker that contained the stock(concentrated) solution. The student notices that there is a little stock solution left in the beaker. However, he decides to go ahead and use the dirty beaker. How will his decision affect the outcome of his results? a. The density will be less, since the density of the solution is now less than 10%.
b. The density will be greater, since the density of the solution is now greater than 10%.
c. This decision will not affect the density, since the majority of the solution is the 10% solution.
d. The density will be the same, since he will estimate how much water needs to be added to the beaker to compensate for the leftover stock solution.

How many moles of al3+ ions are in 1.25 moles of al2o3

Which liquid (h2o, h2o + soap, or h2o + salt) has the strongest cohesion and adhesion? (need now plz)

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
