Chemistry
1 answer:
andre [41]3 years ago
4 0

Answer:

The number of mole is 1.852moles

Explanation:

To calculate the number of mole, using the formula

n = m/Mm

n - number of mole

m - number of mass

Mm - number of molar mass

The molar mass of Re = 186.207

Then, n = 345g/ 186.207g/mol

n = 1.852mol

NaCl has a mc020-1.jpgHfus = 30.2 kJ/mol. What is the mass of a sample of NaCl that needs 732.6 kJ of heat to melt completely?
lilavasa [31]

Answer: The mass of the sample will be 1417.7 grams.

Explanation:

We are given:

\Delta H_{fusion}=30.2kJ/mol

This means that 1 mole of NaCl has an enthalpy of fusion of 30.2 kJ

1 mole of NaCl has a mass of 58.44 grams.

So, 30.2 kJ of heat is require for a mass 58.44 grams of NaCl

So, 732.6 kJ of heat will be required for = \frac{58.44g}{30.2kJ}\times 732.6 kJ = 1417.65 grams of NaCl.

Hence, the mass of NaCl sample will be 1417.7 grams.
