Question

How many moles in 50 grams of CO2 gas?

Answer 1

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

GɪᴠᴇN:

ᴍᴀss = 50 ɢ

ᴍᴏʟᴀʀ ᴍᴀss ᴏғ ᴄᴏ2 = 44

Tᴏ ғɪɴD:

ɴᴏ ᴏғ ᴍᴏʟᴇs ɪɴ 50 ɢ ᴏғ ᴄᴏ2

sᴏʟᴜᴛɪᴏN:

Mᴏʟᴀʀ ᴍᴀss ᴏғ ᴄᴏ2 = 44ɢʀᴀᴍ

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

$ɴᴏ \: ᴏғ \: ᴍᴏʟᴇs = \frac{50}{44}$

$\huge{\boxed{\blue{\bf{ɴᴏ \: ᴏғ \: ᴍᴏʟᴇs = 1.136 }}}}$

Answer 2

Given - Mass of 50 grams

Find - Number of moles in carbon dioxide gas

Solution - Number of moles of carbon dioxide can be calculated using the formula = mass/ molar mass.

Molar mass of carbon dioxide is 44 gram/mole.

So, keeping the values in given formula to find number of moles in given mass of carbon dioxide.

Number of moles = 50/44

Number of moles = 1.14

Hence, number of moles in given mass of carbon dioxide is 1.14.
