Calculate the mass (in g) of solute needed to prepare a solution with the given concentration and volume. a. Sea water has a concentration of approximately 0.60 M sodium chloride. How much
sodium chloride is dissolved in 1.00 L of solution?

b. Coke has a concentration of 0.342 M. What mass of sugar (in g) is dissolved in a 2-L bottle of coke?

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?

a electronegativity decreases beacuse the size of nucleus is bigger.

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
