Marian puts a graduated cylinder marked off in
milliliters on a scale and
resets the scale to zero
so that it will not count
the mass of the cylinder.

Then Marian pours
some water into the
cylinder and records
the volume and mass
of the water.(10ML)

Next, Marian adds
some more water and
records the volume
and mass again.(17 mL)

Finally, Marian calculates
the density of water based
on her measurements.
10.13g/10mL = 1.013 g/mL
17.91g/17mL = 1.054 g/mL
Take the average of the two
measurements:
(1.013 + 1.054) ÷ 2 = 1.034.
So the density of water is
about 1.034 g/mL

Meanwhile, Jamal goes online and finds the
following information on three reliable web sites:The density of
water is 1 g/mL
(one gram per
milliliter).

Which student do you think got the most accurate answer, Marian or
Jamal?

Ineed someone to see if my answers are correct! if any are wrong let me know what the correct answers would be and how to get that answer! 1. how many moles of sodium chloride are in 28 grams od nacl? a. 265 mole naclb. 856 mole naclc. 479 mole of nacld. 1.2 mole nacl < my choice2. 734 grams of lithium sulfate (li2so4) are dissolved to make 2500 ml of solution what is rhe molaratiy? a. 2.67 mb. 4.56 mc. 3.89 m < my choiced. 1.78 m3. how many grams of cacl2 would be dissolved in 3.0 l of a 0.50 m solution of cacl2? a. 250 g cacl2 b. 166.5 g cacl2c. 113.65 g cacl2d. 98 g cacl2 < my choice4. suppose you had 58.44 g of nacl and you dissolved it in exactly 2.00 liters. the molarity if the solution would be 0.5 mtrue < my choicefalse 5. i would need 22g of naoh to make a 3.0 m solution using 250 ml of solvent.true < my choicefalse6. identify the solute: you have a .0195 m solution made from using 6.5 g of solute and 3 l of solvent. identify the solute by solving for molar weight.a. the solute is nacl because the molar weight is 58.43 g/mol < my choiceb. the solute is h2so4 because the molar weight is 98.06 g/molc. the solute is cacl2 because the molar weight is 111.11 g/mol
