How to do the calculation? ?

uming that a skittle has a m of about 1 gram, it would take about 100 moles of skittle to equal the m of the moon . So in comparison with the earths oceans; 1 mole of skittle would fill up the ocean, all of them, many times...... I'm confused somehow I need to prove it what I wrote with calculation ( it's chemistry)... Can someone help me out and please show the steps how you get it thanks.... :)
