(0.102gx1mole)/99g CuCl = 1.031x10^-3 moles
The volume of a sample of water is 20 cm3. The mass of this sample is closest to
Under constant pressure the new volume is (new temp/original temp) x original volume. You first need to convert temp to Kelvin by adding 273 degrees new volume = (771.3) x 297/352 = 650.8 ml
Yes. volume is a measure of how much space a sample of matter takes up!
The gas A has larger volume (x2).
Its density. Density is mass per unit volume.
if unseeded, BOD = (D1-D2)/Pif seeded, BOD = ((D1-D2)-(B1-B2)f)/PD1 = DO of diluted seeded wastewaterD2 = DO of wastewater after incubationB1 = DO of diluted seed sampleB2 = DO of seed sample after incubationf = ratio of seed volume in seeded wastewater test to seed volume in BOD test on seedP = decimal fraction of wastewater sample used. (vol. of wastewater)/(vol. of dilution water plus wastewater)Maybe that helps
It should take just exactly twice the volume to reach the balance point.
The volume of a sample of water is 20 cm3. The mass of this sample is closest to

Dilution factor is the final volume / aliquot volume. Aliquot volume is the measure of sub volume of original sample. Final volume is the total volume. Dilution factor =final volume /aliquot vol. for example ; what is the df when you add 2ml sample to 8m??? total vol is 2+8=10 DF=total vol/aliquot. 10/2=5 So 5 is dilution factor
The volume and the mass of sample both depend on the size of the sample.A small sample has small volume and small mass, a big sample has big volumeand big mass. But the ratio of mass to volume is constant for a pure sample ofa substance, no matter what size the sample is. That ratio is called the densityof the substance.

27.3 g is the mass of an aluminum sample with a volume of 10.0 cm3.
The gas A has larger volume (x2).
Density of a substance = (mass of a sample of it)/(volume of the same sample)
