Cho một thực phẩm có độ ẩm tương đối là 81%, hỏi hoạt độ của nước của thực phẩm đó là bao nhiêu?
spayn [35]

Explanation:

Given a food with a relative humidity of 81%, what is the water activity of that food?

The water activity of a food can be determined by using the formula:

water activity=relative humidity of food / 100

water activity of a food=\frac{relative humidity of food }{100} \\=81/100\\=0.81

Answer:

1) 7.256 mol Br2 (Cl2)/(Br2)

The Br2 cancels out, so we have 7.256(2)

This is 14.512.

2) Number of moles = mass / molar mass

Number of moles = 239.7 g/ 35.5 g/mol

Number of moles =  6.8 mol

BrCl=13.6 mol

13.6(11.5.357)

1568.9 g

3) Repeat the same process with problem 2, given that there are 6.022x10^23 atoms in a mole.

Explanation:

Br2 + Cl2 → 2BrCl

A particular forest is 10,000 acres. Determine its size in hectares. (1 hectare = 2.47
igor_vitrenko [27]

Taking into account the change of units, a particular forest is 4,048.58 hectares.

<h3>Definition of rule of three</h3>

The rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

If the relationship between the magnitudes is direct, the direct rule of three must be applied using the following formula, where a, b and c known data and x the variable to be calculated:

a ⇒ b

c ⇒ x

So: x= (c×b)÷ a

The direct rule of three is the rule applied in this case where there is a change of units.

<h3>Size in hectareas</h3>

To perform in this case the conversion of units, you must first know that 1 hectare = 2.47 acres.

So, the rule of three can be used as follow: if 2.47 acres is 1 hectare, 10,000 acres equals how many hectares?

2.47 acres ⇒ 1 hectare

10,000 acres ⇒ x

So: x= (10,000 acres ×1 hectare)÷ 2.47 acres

Solving:

<u><em>x= 4,048.58 hetares</em></u>

In summary, a particular forest is 4,048.58 hectares.
