Question

Determine how many moles are present in 523.46 g of glucose C6 H12 O6

Answer 1

do you know the molecular weight of glucose !!1:)

Answer 2

180?

Answer 3

moles = gram of glucose / molecular weight of glucose
can u answer now

Answer 4

2.9 mol correct?

Answer 5

that's what I get. if you pay attention to the UNITS of chemistry, the numbers start coming along for the ride, and it gets very easy

Answer 6

bingooooo!!! ur right

Answer 7

Thanks! :)

Answer 8

ur welcome :)

Answer 9

how would i find how many kilograms are in 4 moles of Na2 CO3 then?

Answer 10

moles of Na@CO3 * molecular weight Na2CO3 = gram of Na2 CO3

Answer 11

same way, find the molar mass of one mole, then use dimensional analysis

Answer 12

to get Kg divide gram /1000

Answer 13

0.424?

Answer 14

that's what i get

Answer 15

u should not ask ??? should be bold enough too say that its right now :)
