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.

Find the density of a gas at STP if it’s molar mass is 112g/mol
AleksandrR [38]

Answer:

D= 5 g/L

Explanation:

M= D x Vm

M is the molar mass = 112g/mol

D is the density

Vm is the molar volume whuch is 22.4L at STP

now substitute;

112 = D x 22.4

D= 112\22.4

D= 5 g/L
