Question

if 2.33 × 1023 molecules of a substance have a mass of 23.14 g, what is the molar mass of the substance?

Answer 1

59.8g/mol

Step-by-step explanation:

1 mole will have 6.022 x 10^23 molecules

=> (2.33 x 10^23)/(6.022 x 10^23) = 0.3869 mole

0.3869 mole has mass of 23.14 g

then 1 mole will have = 23.14/0.3869 = 59.8g
