How many moles of O2 are needed to react completely with 35.0 mol C2h2

Chemistry
1 answer:
Wittaler [7]2 years ago
6 0

Hey There!:


2 C2H2 + 5 O2 = 4 CO2 + 2 H2O


2 moles C2H2 ----------- 5 moles O2

35.0 moles C2H2 ------- moles O2


moles O2 = 35.0 * 5 / 2


moles O2 = 87.5 moles


hope this helps!

What is the total mass in grams of 0. 75 mole of so2.
Bas_tet [7]

Answer:

48.075g(or 48g in correct sig figs)***

Explanation:

\frac{0.75mol}{1} *\frac{64.1g}{1 mol}=48.075g

*64.1g is the mass of SO2 which is calculated by simply taking the mass of sulfur and oxygen(but doubling it since there are two oxygens) and adding them together(32.1+2x16.0)

**btw the mol units cancel because of dimensional analysis in case anyone was wondering why

***if your teacher is like mine and specifically wants your answer in correct sig figs, use the answer in parentheses as the original problem only has 2 sig figs

garik1379 [7]

Answer:

    The mass was there all along, it was just in the air. The weight of the oxygen from the air is not weighed in the beginning, only at the end as part of the product, making it seem like there is a total mass change.
