Molars are teeth that are in the back of the mouth. They help one chew food. Other teeth found in the mouth are incisors, canine, and premolars.
Mouth
A molar is one of your larger rearmost teeth found inside your mouth.
To find the moles of As in Na2HAsO4.7H2O, you would first calculate the molar mass of Na2HAsO4.7H2O, then divide the molar mass of As by the molar mass of Na2HAsO4.7H2O to find the moles of As.
It's a tooth used for chewing, back of mouth.
The molar mass of NaCl (sodium chloride) is 58.44 g/mol. To find the molar mass of 3.00 mol of NaCl, you would multiply 3.00 mol by the molar mass of NaCl. For the 1.50 kg, you would first convert the mass from kilograms to grams (1 kg = 1000 g), then divide the mass by the molar mass to find the number of moles.
Molar mass is the sum of all of its elements' average atomic mass in grams. Such as: NH4 would be calculated by adding nitrogen's aam (14.007) and hydrogen's aam multiplied by four (1.0079 x 4 = 4.0316). Therefore, ammonium's molar mass would be (14.007+4.0316) 18.039. Rounded to sig figs.
To find the molar mass of HNO3, you would add up the atomic masses of hydrogen (H), nitrogen (N), and three oxygen atoms (O) in one molecule of HNO3. The molar mass of HNO3 is approximately 63.01 grams per mole.
Molar mass is a term applied for molecules, not for atoms.
To find the molar mass of NH3, you would add up the atomic masses of the atoms it contains. In this case, nitrogen (N) has a molar mass of around 14.01 g/mol and hydrogen (H) has a molar mass of around 1.01 g/mol. Therefore, the molar mass of NH3 would be approximately 14.01 + 3(1.01) = 17.03 g/mol.

The answer is 144,007 g for the anhydrous aluminium chloride.
The molar mass of disulfur pentanitride (S2N5) is 144.19 g/mol. To find the mass, you would need to know the quantity present in moles and then multiply by the molar mass.
