What are the molar heat capacities of: H2O(l) NaCl and Tungsten? I got

75.32 J/K*mol 50 J/K*mol 24.8 J/K*mol

I don't know how accurate you need to be. I convert 4.184 J/*g for H2O to J/mol by moltiplying by 18.015 and it is 75.37. For W I found 24.8 and for NaCl I found 86.4 J/100 g which would be

86.4/100 x 58.44 = 50.49 J/mol*K.

Okay thank you, I was close.

I don't know how good these sites are about providing accurate information.

To determine the molar heat capacities of H2O(l), NaCl, and tungsten, you have provided the following values:

H2O(l): 75.32 J/K*mol
NaCl: 50 J/K*mol
Tungsten: 24.8 J/K*mol

It is important to note that the molar heat capacity is the amount of heat required to raise the temperature of one mole of a substance by one Kelvin (or degree Celsius). Let's explain how to obtain these values:

1. H2O(l) (water):
To determine the molar heat capacity of water, you need to look it up in a reliable source, such as a reference book or scientific database. The value you provided, 75.32 J/K*mol, might have been obtained from a reliable source or a calculated value.

2. NaCl (sodium chloride):
Similarly, to find the molar heat capacity of sodium chloride, you would need to refer to reliable sources. The value you provided, 50 J/K*mol, may have been obtained from a reference book or a calculated value.

3. Tungsten:
Again, to determine the molar heat capacity of tungsten, you would need to refer to reliable sources. Tungsten is a metal, and the value you provided, 24.8 J/K*mol, might have been obtained from a reference book or a calculated value.

When researching molar heat capacities, it is important to rely on reputable sources that provide accurate and up-to-date information. Additionally, it's worth noting that molar heat capacities may vary slightly based on factors such as temperature range and pressure, so this should be taken into consideration when using these values in calculations.
