How many molecules of sodium oxide will be created if 187 grams of oxygen reacts with excess sodium? 4na + o2 -> 2na2o a. 11.69 x 1023 molecules of na2o

Explanation:

1) Balanced chemical equation (given):

2) Mole ratio:

3) Number of moles of O₂ in 187 grams of oxygen:

4) Number of moles of Na₂O:

5) Number of molecules

                                               = 7.04 × 10 ²⁴ molecules ← answer

The answer is rounded to three significant figures.

there is none because earth is stationary and flat.

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
