How many moles of butane do we have if we have 5.50 x 1024 molecules of butane (CH) ?

Dmitry [639]

Answer:

9.14moles

Explanation:

Given parameters:

Number of atoms of butane = 5.5 x 10²⁴atoms

Unknown:

Number of moles = ?

Solution:

To solve this problem, we must understand that a mole of any substance contains the Avogadro's number of particles.

6.02 x 10²³ atoms makes up 1 mole of an atom

5.5 x 10²⁴ atoms will contain = $\frac{5.5 x 10^{24} }{6.02 x 10^{23} }$ = 9.14moles

Calculate the number of moles in 7.4g ca(oh)2

SCORPION-xisa [38]

First find the RFM (Relative Formula Mass) using a periodic table
the RFM of Ca(OH)2 is = 74

then use the equation Moles = Mass / RFM

Moles = 7.4 / 74 = 0.1mol

hope that helps
