At 30°C, a saturated solution of oxygen in water contains 0.130 grams of oxygen in each liter. What is the molarity of oxygen in this solution? (molar mass of 02 = 32)

1. a)c-14 has two more protons

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

3. c) iron and nickel.

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
