Achemistry student must write down in her lab notebook the concentration of a solution of potassium chloride. the concentration of a solution equals the mass of what's dissolved divided by the total volume of the solution. here's how the student prepared the solution: the label on the graduated cylinder says: empty weight: she put some solid potassium chloride into the graduated cylinder and weighed it. with the potassium chloride added, the cylinder weighed . she added water to the graduated cylinder and dissolved the potassium chloride completely. then she read the total volume of the solution from the markings on the graduated cylinder. the total volume of the solution was . what concentration should the student write down in her lab notebook? be sure your answer has the correct number of significant digits.

Microtubular fibers that assist in the movement of chromosomes during nuclear division in conjunction with proteins, makes up the small and large organelle pieces that assemble prior to translation three-base nucleotide sequence that can complementarily pair with the functional transcript, allowing a particular material to be brought to a ribosome particular time in the cell cycle when the cell’s systems determine if the cellular conditions are appropriate to continue through the cycle time in the cell’s cycle when proteins are made and organelles are duplicated enzyme that allows proper nucleotide bonding during transcription specific dna sequence which will initiate gene transcription division of the cell’s cytoplasm specific bond that forms between two amino acids when a carboxyl group binds to a amino group three-base sequence that does not code for a particular amino acid a paired organelle which facilitates the formation of movement microtubules time in the cell’s cycle when the microtubular structures exert an equal pressure on the cell’s genetic material
