How many moles of C6H12O6 will be produced if 22 grams of CO2 are reacted
SSSSS [86.1K]

Answer:

60 grams

Explanation:

We have the balanced equation (without state symbols):

6

H

2

O

+

6

C

O

2

→

C

6

H

12

O

6

+

6

O

2

So, we would need six moles of carbon dioxide to fully produce one mole of glucose.

Here, we got  

88

 

g

of carbon dioxide, and we need to convert it into moles.

Carbon dioxide has a molar mass of  

44

 

g/mol

. So here, there exist

88

g

44

g

/mol

=

2

 

mol

Since there are two moles of  

C

O

2

, we can produce  

2

6

⋅

1

=

1

3

moles of glucose  

(

C

6

H

12

O

6

)

.

We need to find the mass of the glucose produced, so we multiply the number of moles of glucose by its molar mass.

Glucose has a molar mass of  

180.156

 

g/mol

. So here, the mass of glucose produced is

1

3

mol

⋅

180.156

 

g

mol

≈

60

 

g

to the nearest whole number.

So, approximately  

60

grams of glucose will be produced.

Caption for this picture asap.
miss Akunina [59]
I will walk through different captions if one I say isn’t correct.
1) As the humans impact the environment, there will be consequences such as global warming. 2) When the long-term consequences has come, human life would become more difficult and complicated.
3) If the himan life hasn’t taken care of the global, it wouldn’t be safe and consequences would attracted by this cause. (As said above.)
Thank you!

lucose, a major energy-yielding nutrient, is present in bacterial cells at a concentration of approximately 0.200 mM. i) What is
Mkey [24]

Answer:

The concentration is 0.036 mg/mL

Explanation:

Concentration = 0.2 mM = 0.2/1000 = 2×10^-4 M = 2×10^-4 mol/L × 180,000 mg/1 mol × 1 L/1000 mL = 0.036 mg/mL
