What is the atomic mass of neon to the nearest tenth

help me pls

If the atomic mass of an atom is 34 and the atom contains 13 protons, how many neutrons does the atom contain?

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.

In the space, show a correct numerical setup for calculating the number of moles of co2 present in 11 grams of co2
