------------------------------------------------ NaCl is 35.8 kg and water is 100 kg. Calculate the kilomoles of NaCl per 1000 kg of water and explain the steps.

To calculate the kilomoles of NaCl per 1000 kg of water, we use the molar mass of NaCl, which is 58.5 g/mol, and the given mass of NaCl (35.8 kg) to find the moles of NaCl. Converting this to kilomoles and dividing by 1000 kg of water, we get 0.612 kmol NaCl/kg water.

To calculate the kilomoles of NaCl per 1000 kg of water, we first need to know the molar mass of NaCl. The molar mass of sodium (Na) is 23.0 g/mol, and the molar mass of chlorine (Cl) is 35.5 g/mol. Therefore, the molar mass of sodium chloride (NaCl) is 23.0 g/mol + 35.5 g/mol = 58.5 g/mol.

We are given the mass of NaCl as 35.8 kg, which is equivalent to 35800 grams (since 1 kg = 1000 grams). We can then calculate the number of moles of NaCl:

Number of moles of NaCl = mass of NaCl / molar mass of NaCl

= 35800 g / 58.5 g/mol

= 612.0 mol NaCl.

Now, since we are interested in the ratio per 1000 kg of water, we have:

Kilomoles of NaCl per 1000 kg of water = (612.0 mol NaCl) / (1000 kg water)

= 0.612 kmol NaCl/kg water.
