You have 4.5 x 10^24 particles of C3H8. How many grams are present?
Citrus2011 [14]

Answer:

33 g.

Explanation:

Hello there!

In this case, for these particle-mole-mass relationships problems, it is necessary for us to recall the following equivalence statement, based off the molar mass of the involved compound, C3H8, one mole of particles and the Avogadro's number:

1mol=44.11g=6.022x10^{23}molecules

In such a way, we can set up the following expression for the calculation of the mass in the given particles of propane:

4.5x10^{23}molecules*\frac{1mol}{6.022x10^{23}molecules} *\frac{44.11g}{1mol}\\\\33g

Best regards!
