ing Sapling Learning What is the mass (in grams) of 9.69 x 10 molecules of methanol (CHjOH)? Next Exit

Solution

According to avogadro\'s law 1 mole substance contain 6.022 X 10²³ molecule therefore 9.69 X10²⁴ molecule of methanol = 9.69 X10²⁴ / 6.022 X 10²³ = 16.09 mole

molar mass of methanol = 32.04 g/mol

then 16.09 mole of methanol = 32.04 X 16.09 = 515.56 gm

mass of  9.69 X10²⁴ molecule of methanol = 515.56 gm
