The mass in grams 550 mL of salt water with a density of 1.50 g/cm³ is 825grams.
<h3>DENSITY:</h3>
- The mass of a substance can be calculated by multiplying the density of the substance by its volume. That is;
Mass = density × volume
- According to this question, the volume of the salt is 550mL while its density is given as 1.50g/mL. The mass is calculated as follows:
Mass = 1.50g/mL × 550mL
Mass = 825grams.
Therefore, the mass in grams 550 mL of salt water with a density of 1.50 g/cm³ is 825grams.

Answer:
alkenes
nucleophiles
electrophiles
syn
anti
syn and anti
Explanation:
Compounds that contain a carbon-carbon double bond are known as <u>alkenes</u>
Alkenes are electron rich; therefore, simple alkenes do not react with <u>nucleophiles</u> or bases, but will react with <u>electrophiles</u> or acids.
In the IUPAC system, an alkene is identified by the suffix -ene-
Addition reactions in which two parts Of a reagent are added to the same side of
a double bond are known as <u>syn </u>additions.
Addition reactions in which two parts of a reagent are added from opposite
sides of a double bond are called <u>anti</u> additions
Halogenation and halohydrin formation occur with <u>syn and anti</u> -additions.
Further explanations:
Compounds that contain a carbon-carbon single bond are known as alkanes. Compounds that contain a carbon-carbon double bond are known as alkenes. Compounds that contain a carbon-carbon triple bond are known as alkynes.
Nucleophiles are electron rich so they react with electron deficient centers while Electrophiles are electron deficient so they react with electron rich centers.
The normality of the H₂SO₄ that reacted with 25cc of 5 % NaOH solution is 1.1 N.
<h3>What is the molarity of 5% NaOH?</h3>
The molarity of 5% NaOH is 1.32 M
25 cc of NaOH neutralized 30cc of H₂SO₄ solution.
Equation of reaction is given below:
- 2 NaOH + H₂SO₄ ---> Na₂SO₄ + 2 H₂O
Molarity of H₂SO₄ = 1.32 x 1 x 25/(30 x 2) = 0.55 M
- Normality = Molarity × moles of H⁺ ions per mole of acid
moles of H⁺ ions per mole of H₂SO₄ = 2
Normality of H₂SO₄ = 0.55 x 2 = 1.1 N
In conclusion, the normality of an acid is determined from the molarity and the moles of H⁺ ions per mole of acid.
