Question

how many moles are there in 20 gram of CO2
​

Answer 1

$\huge{\boxed{\red{\bf{Answer:-}}}}$

GɪᴠᴇN:

• ᴍᴀss = 20 ɢ

• ᴍᴏʟᴀʀ ᴍᴀss ᴏғ ᴄᴏ2 = 44

Tᴏ ғɪɴD:

• ɴᴏ ᴏғ ᴍᴏʟᴇs ɪɴ 20 ɢ ᴏғ ᴄᴏ2

sᴏʟᴜᴛɪᴏN:

Mᴏʟᴀʀ ᴍᴀss ᴏғ ᴄᴏ2 = 44ɢʀᴀᴍ

$ɴᴏ \: ᴏғ \: ᴍᴏʟᴇs = \frac{mass}{molar \: mass}$

$ɴᴏ \: ᴏғ \: ᴍᴏʟᴇs = \frac{20}{44}$

$\huge{\boxed{\blue{\bf{ɴᴏ \: ᴏғ \: ᴍᴏʟᴇs = 0.45 }}}}$
