In the equation: 2H2 + O2 --> 2H2O

What mass of Hydrogen Gas will completely react with 4 moles of Oxygen gas

(Hint: going from moles to mass of another compound)
A)8 g
B)16 g
C)24 g

B) 16 g

Explanation:

First we convert 4 moles of O₂ into moles of H₂, using the stoichiometric coefficients of the balanced reaction:

Finally we convert 8 moles of H₂ into grams, using its molar mass:

Thus, the correct answer is option B).

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

the temperature of the gas, in k, not celsius.
