Remember, number of moles = mass / molar mass. Therefore, molar mass = mass / moles. You can plug in the numbers...but don't forget the significant figures will be 3!

The molar mass is the mass in line with unit mole Its gadgets are g/mol So if we divide mass (grams) via molar mass (grams in line with mole) we are left with purely moles M = m/n so n = m/M the place M is the molar mass and m is the mass of the substance.

0.537X = 181
Solve for X by dividing both sides by 0.537

just divide the mass by the number of moles

181/.537=337.05g/mol
