Question

The chemical equation below shows the reaction between carbon dioxide (CO2) and lithium hydroxide (LiOH).

CO2 + 2LiOH mc011-1.jpg Li2CO3 + H2O

The molar mass CO2 is 44.01 g/mol. How many moles of LiOH are needed to react completely with 25.5 g of CO2?
0.290
0.579
1.16
1.73 @Somy @sweetburger @iPwnbunnies

Answer 1

CO2 + 2LiOH = Li2CO3 + H2O

Answer 2

isnt it 0.0290

Answer 3

did u calculate it or guessed?

Answer 4

guessed
dont understand it

Answer 5

not gonna work

Answer 6

alright
r u familiar with this formula
mole= mass/Molecular mass?

Answer 7

nah

Answer 8

@Somy

Answer 9

hhh well then im telling you
mole= mass/Molecular mass
both mass and molecular masses for CO2 are given
put them in the formula and get mole for CO2

Answer 10

so 1.16?

Answer 11

~_~ how did u get it?

Answer 12

i guesssed dont undestand this unit at all

Answer 13

=_= hhh
mole= 25.5/44.01 =0.579 mole of CO2
and ratio between CO2 and LiOH is 1:2
1----0.579mole
2---- x
x= 2*0579 =

Answer 14

x= 2*0579 = gives me 1.158

Answer 15

@Somy

Answer 16

yes yes

Answer 17

thats not an option tho

Answer 18

well if you round it it'll be in the option ~_~

Answer 19

1.16

Answer 20

yup)
