Answer:

The **total mass **of the **solution **of **lithium****nitrate **solution has been **99.7 grams.**

**Density **can be **defined **as the **mass **of the **solute** per **unit volume**. The **density **can be expressed as **g**/**ml **or kg/L.

The **mass **of given **Lithium nitrate **=** 2.5 **grams.

The **mass **of **water **can be given as:

**Density **=

**Volume **of water = **97.2 ml.**

The **total mass **of **solution:**

**Mass **of **water **= Density Volume

Mass of **water **= 1 97.2 grams

**Mass **of **water **= **97.2 grams**

The **total mass **= Mass of lithium nitrate + mass of water

= 2.5 + 97.2 grams

= **99.7 grams.**

The **total mass **of the **solution **of **lithium****nitrate **solution has been **99.7 grams.**

For more information about **density**, refer to the link:

Answer:

**Answer:**

**The total mass of the solution = 99.7 g**

Note: The question is incomplete. The complete question is given below:

*A "coffee-cup" calorimetry experiment is run for the dissolution of 2.5 g of lithium nitrate placed into 97.2 mL of water. The temperature of the solution is initially at 23.5oC. After the reaction takes place, the temperature of the solution is 28.3 oC. *

*1. Using a density of 1.0 g/mL for the water added and adding in the mass of the lithium nitrate, what is the total mass of the solution and solid?*

**Explanation:**

mass = density * volume

density of water = 1.0 g/mL; volume of water = 97.2 mL

mass of water = 1.0 g/L * 97.2 mL

mass of water = 97.2 g

mass of lithium nitrate = 2.5 g

A solution is made by dissolving a solute (usually solid) in a solvent (usually a liquid). The solute in this reaction is lithium nitrate and the solvent is water.

Total mass of solution = mass of water + mass of lithium nitrate

Total mass of solution = 97.2 g + 2.5 g = 99.7 g

**Therefore, total mass of the solution = 99.7 g**

**Answer:**

your boddy is made of mater and a clock too it is still a mater of time.

**Explanation:**

Answer:

The concentration is 0.036 mg/mL

Explanation:

Concentration = 0.2 mM = 0.2/1000 = 2×10^-4 M = 2×10^-4 mol/L × 180,000 mg/1 mol × 1 L/1000 mL = 0.036 mg/mL

**Answer:**

Hence,

1) removed

2) drained through the stopcock

3) get eye level with

4) slow the draining

5) switch to a new flask

**Explanation:**

After mixing the solutions in a separatory funnel, the stopper should be **removed** and the liquid should be **drained through the stopcock,** and the layers allowed to separate. When you get close to the interface between the layers, **get eye level with** the funnel and turn over to **slow the draining** heat up until the first layer is collected. **Switch to a new flask** get eye level with it to collect the second layer.

**Answer**

Naphthalene is a non electrolyte

If the unknown compound is an electrolyte it gives 2 or more ions in solution

( NaCl >> Na+ + Cl- => 2 ions

Ca(NO3)2 >> Ca2+ + 2 NO3- => 3 ions)

the f.p. lowering is directly proportional to the molal concentration of dissolved ions in the solution )

For naphthalene

delta T = 1.86 x m

for a salt that gives 2 ions

delta T = 1.86 x m x 2

hence the lowering in freezion point of unkown is greater then napthalene

Answer: 1.037M

Explanation:

Since the rate constant unit is per seconds, therefore it is a first order reaction.

First order reaction equation is given as

InA= -kt +InAo

Where,Ao is the initial concentration of reactant =0.600M

A is the concentration of reactant at a specifies time t=3×60=180s

and k is the rate constant

InA = -6.50×10^-3 ×180 +In(0.6)

InA = -1.17 + 0.5108

InA= -1.680

A = e-1.680

A= 1.037M

Therefore the concentration after 3minutes is 1.037M

The answer I got was False, is this correct?

**Answer: yes it is false**

**Explanation:**

The statement is false. A synthetic process with a lower E-factor produces less waste than a process with a higher E-factor.

The E-factor is a measure of the waste generated during a manufacturing process. It is calculated by dividing the total mass of waste produced by the mass of the desired product. A lower E-factor indicates that less waste is generated per unit of product.

In this case, the synthetic process with an E-factor of 3.0 produces less waste than the process with an E-factor of 17.4. This means that the process with an E-factor of 3.0 is more efficient in terms of waste reduction.
