Question

What is the mass of a sample of acetylene gas (C2H2)that contains 4.44 x 1034 atoms of carbon?

Also, Im not sure how to convert from moles of C to moles of C2H2.

Answer 1

If 10g of NO react with 20g of O2, what is the maximum amount of NO2 that can be produced?

Answer 2

4.44E34 atoms C x (1 mol C/6.02E23 atom C) x (1 mol C2H2/2 mols C) x (26 C2H2/1 mol C2H2) = ?

Note:
4.44E34 atoms C x (1 mol C/6.02E23 atoms C) converts atoms C to mols C atoms.

? x (1 mol C2H2/2 mols C) converts mols C atoms to mols C2H2 molecules.

? x (26 C2H2/1 mol C2H2) converts mols 2CH2 molecules to grams C2H2.
