Question

calculate the formula unit mass of NaHCO3 (Na =23u H =1u C=12u O = 16u

Answer 1

ɢɪᴠᴇɴ ᴄᴏᴍᴘᴏᴜɴᴅ :

ɴᴀʜᴄᴏ3

= ᴍᴀss ᴏғ ɴᴀ + ᴍᴀss ᴏғ ʜ + ᴍᴀss ᴏғ ᴄ + 3 × ᴍᴀss ᴏғ ᴏ

= 23 + 1 + 12 + 3 × 16

= 23 + 1 + 12 + 48

= 84 ᴜ

Answer 2

Answer:

Formula Unit mass of NaHCO3=  

mass of Na + mass of H + mass of C + mass of O

= 23 + 1 + 12 + 3(16)

= 23 + 1 + 12 + 48

= 84 u
