Answer: here you go mate
Explanation: molar mass of ethanol = 46 g
No. of moles of ethanol = 0.046 /46
= 1 × 10^-3
No. of molecules of ethanol = 1 × 10^-3 × 6.023 × 10^23 = 6.023 × 10^20
Each ethanol ( C2H5OH) contains 6 hydrogen atoms
so no. of hydrogen atoms in 0.046 g of ethanol = 6.023 x 10^20 ×6
= 3.6138 x 10^21
