When two molecules of methanol (CH3OH) react with oxygen, they combine with three O2 molecules to form two CO2 molecules and fou

Alex17521 [72]

Answer:

188

Explanation:

For every 2 molecules of methanol reacted, 4 molecules of water are formed. Use this relationship to solve.

2/4 = 94/x

2x = 376

x = 188

188 molecules of water will be formed.

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.
