Answer:

a) ppm

b) ppm

c) ppb

d) ppt

e) ppb

Explanation:

a) You know that 1000 g are 1 kg, and 1000 kg are 1 ton, so (1000)*(1000) g are 1 ton, so 1,000,000 grams are one ton.

b) 1000 mg are 1 g, and 1000 g are 1 liter, so 1,000,000 grams are one liter.

c) You know that 1000 ug are 1 mg, so with the b), we just need to multiply the answer by 1000, so 1,000,000,000 ug are 1 liter.

d) The same as c, 1000 ng are 1 mg. So we are talkinf of ppt.

e) 1000 mg are 1 g. And 1000 g are 1 kg, then 1000 kg are one ton. So 1,000,000,000 mg are one ton.

The total number of valence electrons in a molecule of sof2 is ________.
tamaranim1 [39]
Answer:
            There are 26 valence electrons in SOF₂.

Explanation:
                   Valence electrons are calculated by adding the valence electrons present in valence shell of each element present in SOF₂. So,

# of Valence e⁻s in S  =  6

# of Valence e⁻s in O  =  6

# of Valence e⁻s in F  =  7

# of Valence e⁻s in F  =  7

Now, add all valence electrons,

                                =  6 + 6 + 7 + 7

                                =  26 Valence Electrons

Nimfa-mama [501]

Answer:

9.606 grams of citric acid are present in 125 mL of a 0.400 M citric acid solution.

Explanation:

Molarity : It is defined as the number of moles of solute present in one liter of solution.  Mathematically written as:

Molarity=\frac{\text{Moles of solute}}{\text{volume of solution in L}}

Moles of citric acid  = n

Volume of the citric acid  solution = 125 mL  =125 × 0.001 L= 0.125 L

(1 mL = 0.001L)

Molarity of the citric acid  solution = 0.400 M

0.400 M=\frac{n}{0.12 5L}

n  = 0.400 M × 0.125 L = 0.05 moles

Mass of 0.05 moles of citric acid :

0.05 mol\times 192.12 g/mol=9.606 g

9.606 grams of citric acid are present in 125 mL of a 0.400 M citric acid solution.
