130 ppm will contain  0.12985167 grams of chlorine present in per liter of pool water.

<h3>What is ppm?</h3>

This is an abbreviation for "parts per million" and it also can be expressed as milligrams per liter (mg/L).

1001.142303 ppm is equal to 1 g/L

So, 130 ppm will contain  \frac{130}{1001.142303} grams of chlorine present in per liter of pool water which is equal to 0.12985167 gram/L.

Each student in a class placed a 2.00 g sample of a mixture of Cu and Al in a beaker and placed the beaker in a fume hood. The s
Aleks [24]

Answer:

Percentage mass of copper in the sample = 32%

Explanation:

Equation of the reaction producing Cu(NO₃) is given below:

Cu(s)+ 4HNO₃(aq) ---> Cu(NO₃)(aq) + 2NO₂(g) + 2H₂O(l)

From the equation of reaction, 1 mole of Cu(NO₃) is produced from 1 mole of copper. Therefore, 0.010 moles of Cu(NO₃) will be produced from 0.010 mole of copper.

Molar mass of copper = 64 g/mol

mass of copper = number of moles * molar mass

mass of copper = 0.01 mol * 64 g/mol = 0.64 g

Percentage by mass of copper in the 2.00 g sample = (0.64/2.00) * 100%

Percentage mass of copper in the sample = 32%

How to sold equation with periodic table of elements?​
Illusion [34]

In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal

What is the concentration in mol L-l of a 12% solution of tetrahydrate magnesium chloride (MgCl2)?
madreJ [45]

The concentration in mol L-l (M) = 0.717

<h3>Further explanation</h3>

Given

12% solution of tetrahydrate magnesium chloride (MgCl₂)

Required

The concentration

Solution

Tetrahydrate magnesium chloride (MgCl₂)⇒MgCl₂.4H₂O

MW = Ar Mg+2. Ar Cl+8. Ar H + 4. Ar O

MW=24.31 + 2 x 35.45 + 8 x 1.01 + 4 x 16

MW=24.31+70.9+8.08+64

MW=167.29 g/mol

12% solution = 12 % m/v = 12 g in 100 ml solution

For 1 L solution :

\tt \dfrac{1}{0.1}\times 12~g=120~g

The concentration in g/L = 120 g/L

Convert grams to moles :

\tt mol=\dfrac{120}{167.29}=0.717
