cell membrane
Explanation:
it controls what comes and goes out of a cell
Answer:

Explanation:
Hello,
In this case, since in a dilution process the moles of the solute must remain unchanged, we use the volumes and molarities as shown below:

Clearly, the concentrated solution is 7.00M and the diluted solution is unknown, thus, the concentration of the diluted solution after the dilution to 100 mL is:

Best regards.
Maybe it's [Acid] and [H+ ions]
Explanation:
mass = no. of moles x molar mass (Mr)
i- mass = 10.2 mol x 30 g/mol
= 306 g
ii- mass of potassium hydroxide = 0.0146 mol x 56g/mol
= 0.8176g
mass of calcium hydroxide= 0.0146mol x 74 g/mol
= 1.0804g
