What is the mass of hydrogen in 50.0 g of propane, c3h8? 9.1 g44.0 g18.2 g81.8 g

9.1 g

Explanation:

To calculate the moles, we use the equation:

For

Given mass = 50.0 g

Molar volume of   = 44 g/mol

Putting values in above equation, we get:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number of particles.

1 mole of contains 8 moles of hydrogen

1.14 moles of contains = moles of hydrogen

Mass of hydrogen=

Thus the mass of hydrogen is 9.1 grams.
