1 M = 1 mol/leter solution
so 2.5 mol sucrose
molar mass of sucrose is (mass carbon=12)x(mol carbon=12)+(mass hydrogen=1)x(mol hydro.=22)+(mass oxygen=16)x(mol oxy.=11) = 342g/mol
mass sucrose = moles sucrose x molar mass sucrose = 2.5 mol x 342g/mol = 855 grams sucrose
you just got an A on this one
people born into a good lifestyle stay comfortable in that lifestyle
therefore they have no need to struggle
thats the basis of primape instinct
make a lifstyle that's better for their offspring so they need to do that much less work to advance the spcies as a whole
fyi. humans are primapes
