You will create 1.000L of 100.0 ppm stock solution of Acetylsalicylic acid (ASA, from the pure powder) in a 2 (v/v) % HCl in this lab. 2 (v/v) % HCl means the volume of concentrated HCl and the volume of the diluted HCl is 2:100. Determine the mass of the solute and volume of conc. HCl you are going to weigh out or measure with a graduated cylinder. Show your calculation.

May someone me with these science questions

What was bohr’s contribution to the planetary model

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
