If 342.2 grams of C12H22O11 (sucrose) is dissolved in 1.0 L of solution. What is the molar concentration of the solution? Report your answer with the correct number of significant figures.

Answers

Answer 1

Answer:

M = 1 M

Explanation:

Given data:

Mass in gram = 342.2 g

Volume of solution = 1.0 L

Molar concentration = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

Number of moles of sucrose:

Number of moles = mass/molar mass

Number of moles = 342.2 g/ 342.2 g/mol

Number of moles = 1 mol

Molarity:

M = 1 mol / 1.0 L

M = 1 mol/L

M = 1 M

Answer 2

The molar concentration of the solution is :

- M = 1 M

Check below to see the full solution.

Molar Concentration

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

What information do we have?

Mass in gram = 342.2 g

Volume of solution = 1.0 L

Molar concentration = ?

Number of moles of sucrose:

Number of moles = mass/molar mass

Number of moles = 342.2 g/ 342.2 g/mol

Number of moles = 1 mol

Molarity:

Molarity = number of moles of solute / L of solution

M = 1 mol / 1.0 L

M = 1 mol/L

M = 1 M

At his favorite restaurant, Dylan orders a soda with his dinner. The ice in his drink has a mass of 6 g and a volume of 20 cm3. What is the density of the ice? Explain the steps you took to solve this problem, showing your work.

Answers

Answer: d =  0.3 g/cm³ Explanation: Density: Density is equal to the mass of substance divided by its volume. Units: SI unit of density is Kg/m3. Other units are given below, g/cm3, g/mL , kg/L Formula: D=m/v D= density m=mass V=volume Symbol: The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density. Given data: Mass = 6 g Volume = 20 cm³ Density = ? Solution: d = m/v d = 6g/20 cm³ d =  0.3 g/cm³

Answer:

C

Explanation:

Based on the synthesis reaction,the product of the given chemical equation is NaCuPO4 .

What is chemical equation?

Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.

A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .

The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.
