What is the mass in grams of 0.338 mol of glucose (c6h12o6)? step by step

The amount in mole of a substance = mass in gram * (1 mole of the substance/ molar mass of the substance).
molar mass of C6H12O6 = (12*6) + (1*12) + (16*6) = 180.
Let the mass of glucose in gram = G
0.338 = G X (I/180)
0.338 = G/180 
G = 0.338 X 180 = 60.84g.

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
