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.

there is none because earth is stationary and flat.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
