How many moles of NaCl are in 16.0 grams of NaCl?

16.0g divided by 58g = 0.28 moles

moles = g/molar mass

Well, that depends... are we talking about moles of the furry little creatures that dig underground tunnels or moles in chemistry? Just making sure we're on the same page here.

To determine the number of moles of NaCl in 16.0 grams, we need to use the formula:

Number of moles = Mass / molar mass

First, let's find the molar mass of NaCl. The molar mass of sodium (Na) is 22.99 g/mol, and the molar mass of chlorine (Cl) is 35.45 g/mol.

The molar mass of NaCl is therefore:
Molar mass = (Na molar mass) + (Cl molar mass)
Molar mass = 22.99 g/mol + 35.45 g/mol
Molar mass = 58.44 g/mol

Now, we can use the formula to find the number of moles:
Number of moles = Mass / molar mass
Number of moles = 16.0 g / 58.44 g/mol

Calculating this division:
Number of moles = 0.274 moles

Therefore, there are approximately 0.274 moles of NaCl in 16.0 grams of NaCl.

To calculate the number of moles of NaCl in 16.0 grams of NaCl, you need to use the formula:

moles = mass / molar mass

First, you need to find the molar mass of NaCl. The molar mass is the sum of the atomic masses of all the atoms in a molecule. The atomic mass of sodium (Na) is 22.99 grams/mole, and the atomic mass of chlorine (Cl) is 35.45 grams/mole.

The molar mass of NaCl can be calculated as follows:

molar mass = (atomic mass of Na) + (atomic mass of Cl)
= 22.99 g/mol + 35.45 g/mol
= 58.44 g/mol

Now, you can plug the values into the formula to find the number of moles:

moles = 16.0 g / 58.44 g/mol
≈ 0.274 moles

Therefore, there are approximately 0.274 moles of NaCl in 16.0 grams of NaCl.
