we did a lab thing in chemestry and one of the questions is::

"" Calculate the moles of chicken fat in the sample (MWfat = 797.7 g/mol""
MASS = .9933g

"" calculate the moles of sucrose (C12 H22 O11) in the sample MWsucrose = 342.2g/mol)
MASS = 1.0108g

"" calculate the moles of TNT in the sample (MWtnt = 227.13 g/mol)""
MASS = 1.0764g

how would you calculate the moles?? i know you need the mass but i forget how...
