Answer:
Nonpolar Solvent. Carbon tetrachloride. CCl4
Explanation:
The other compounds listed are polar;
polar substances are by their nature more soluble in Other polar compounds. NH3 is a gas; so unless it was a very specific compound you needed in ammonia gas, it, being also polar as well as a gas would not be a good choice for this question.
Kilograms is the SI unit for mass
Answer:
oxygen
Explanation:
The given isotope has 8 protons and 8 electrons, so the atomic number of the given isotope is 8, which is the atomic number of oxygen.
<em>V = 151 mL = 151 cm³</em>
<em>d = 0,789 g/mL = 0,789 g/cm³</em>
--------------------------------------
d = m/V
m = d×V
m = 0,789×151
<u>m = 119,139g</u>
