The approximate minimum daily dietary requirement of the amino acid leucine, C6H13N02, is 1.1 g. What is this requirement in moles?

What is the number of moles of chemical units represented by 9.03x10^24? and how do i show work? (dumb it down )

The excretory system,need answers for all: )

The table lists the lattice energies of some compounds.compoundlattice energy (kj/mol)lif            –1,036licl            –853naf            –923kf            –821nacl            –786which statement about crystal lattice energy is  best  supported by the information in the table? the lattice energy increases as cations get smaller, as shown by lif and kf.the lattice energy increases as the cations get larger, as shown by lif and licl.the lattice energy decreases as cations get smaller, as shown by nacl and naf.the lattice energy decreases as the cations get smaller, as shown by naf and kf.
