Answer:
1/100 mol of glucose = 6.022 X 10 ^ 21 molecules of glucose
Explanation:
molar weight of glucose = 180g/mol
as,
6 [c] + 12[h] + 6[o]
= 6[12] +12[1] + 6[16]
= 72 + 12 + 96 = 180g/mol
P.S. these are approximates, mass of carbon is actually 12.011, of hydrogen is 1.008 and of oxygen is 15.999
no of mol = given mass / molar mass
= 1.8g/180g/mol = 1/100 mol = 6.022 X 10 ^ 21
