Answer:

E=2052.8 kJ

Explanation:

The energy absorbed by the water is the energy it requires to evaporate. So:

Heat of .vap= 40.65 kJ/mol

The moles of water:

n_w=m_w *\frac{1000g}{2.2lbs}*\frac{1}{M}

M is the water molecular weight

n_w=2 lbs *\frac{1000g}{2.2lbs}*\frac{1}{18g/mol}

n_w=50.5mol

The energy absorbed:

E=n_w*Heat of vap.=50.5mol *40.65 kJ/mol

E=2052.8 kJ

How many atoms are in the 1.5 moles of tin atoms?
Anastasy [175]

Answer:

option C = 9.0 x 10²³ atoms

Explanation:

Data Given:

no. of moles of tin (Sn) atoms = 1.5 moles

no. of tin (Sn) atoms = ?

Solution:

Formula used to find number of atoms

                  no. of moles = no. of atoms / Avogadro's number

Rearrange the above equation:

          no. of atoms =   no. of moles x Avogadro's number . . . . . . (1)

Where

Avogadro's number = 6.022 x 10²³

Put values in equation 1

           no. of atoms = 1.5 x 6.022 x 10²³

           no. of atoms = 9.033 x 10²³

Round the figure = 9.0 x 10²³ atoms

So option C is correct
