Answer: 18.2


Explanation:

1) Chemical equation: <span>C₆ H₁₂ O₆ (s) + 6O₂ (g) ---> 6CO₂ (g) + 6H₂O(l)</span>

2) Mole ratio: 6 moles <span>C₆ H₁₂ O₆ : 6 mol O₂</span>

6:6 is the same that 1:1. This is, each molecule of <span>C₆ H₁₂ O₆ is burned with one mole of O₂.</span>

3) Conclusion:

Therefore, 18.2 moles of <span>C₆ H₁₂ O₆ can be burned with 18.2 moles of O₂</span>

Answer:
              547.7 g of C₆H₁₂O₆

Solution:
               The balance chemical equation is as follow,

                           C₆H₁₂O₆  +  6 O₂    →    6 CO₂  +  6 H₂O

According to equation,

                         6 moles of O₂ burns  =  180.56 g of C₆H₁₂O₆
So,
                18.2 moles of O₂ will burn  =  X g of C₆H₁₂O₆

Solving for X,
                      X  =  (18.2 mol × 180.56 g) ÷ 6 mol

                      X  =  547.7 g of C₆H₁₂O₆

How many grams are in 4.0 moles of lithium
Fittoniya [83]

Answer:

The correct answer is 27.764 grams.

Explanation:

A standard scientific unit for determining the large quantities of very small entities like molecules, atoms, or other specific particles is termed as a mole. The molecular weight of lithium is 6.941 grams per mole. Thus, one mole of lithium has 6.941 grams.

If, 1 mole of Li has 6.941 grams, then 4 moles of Lithium will have,

= Molecular mass of lithium/1 mole * 4 mole

= 6.941 gram per mole/1 mole * 4 moles.

= 27.764 grams

G.com what is the mass of a gold bar that is 7.379 × 10–4 m3 in volume
tiny-mole [99]
<span>7.379 * 10^(-4) is measured, hence prone to error, either human error or via measuring device. In this case,
100 cm = 1 m is written in stone and is unquestionable.
 The density of the gold is 19.3 g/cm^3 and could be an approximation.
 The approximation is good to at least one night.</span>

Genetic equilibrium is the state in which allele frequencies do<br> not change in a<br> Check it
Vikentia [17]

Answer:

Genetic equilibrium is the state in which allele frequencies do

not change in a generation over generation.

Explanation:

Genetic equilibrium can be described as a situation which arises when a certain allele or genotype remains constant for a species generation over generations. Genetic equilibrium can be maintained if no external factors like mutations affect the population of the species. The phenomenon of natural selection and evolution need to be stopped if a genetic equilibrium is to be maintained. Hardy-Weinberg theorem is the mathematical depiction of genetic equilibrium.
