Molarity of a solution if 124.86 g of rbf are dissolved into a solution of water that has a final volume of 2.00L is 0.59.

<h3>What is molarity?</h3>

Molarity is used for dilute aqueous solutions held at a constant temperature. In general, the difference between molarity and molality for aqueous solutions near room temperature is very small and it won't really matter whether you use a molar or molal concentration.

MOLARITY = no of moles of solute/volume of soln in litres

No of moles of rbf = 124.6/104.46

= 1.19

Volume of soln = 2

Molarity=1.19/2 = 0.59

What two factors must be held constant for density to be a constant ratio?
Neko [114]

Answer:

Temperature and Pressure

Explanation:

Temperature and pressure cause change in volume.

So any change in volume will alter the ratio of density as given by equation of density.

Density = mass/ volume

Change in volume will alter the ratio.

Kindly mark it branliest if the answer is little bit satisfying.

Coach is used to activate carboxylic acids. what type of compound is formed between coach and a carboxylic acid?
MrMuchimi

The  type of compound is formed between coach and a carboxylic acid alcohol + carboxylic acid → ester + water.

How carboxylic acids are formed?

A acid is produced after the acidic hydrolysis of esters and carboxylates are produced after the basic hydrolysis of an ester.

What are the functional group of alcohol and carboxylic acid?

Alcohols contain the hydroxyl functional group and may be primary, secondary, or tertiary. Ethers are compounds with an oxygen atom bonded to 2 alkyl groups. Aldehydes and ketones contain the carbonyl functional group

Can a compound be a acid and an alcohol?

Esters are represented by the formula RCOOR', where R and R' are hydrocarbon groups. The ester, which is compound derived from a carboxylic acid and an alcohol in which the OH of the acid is replaced by an OR group, looks somewhat sort of a n ether and also somewhat like a carboxylic acid.

pav-90 [236]

Answer:

Average atomic mass = 6.6575.

Explanation:

As fractions the abundance is 1/4 and 3/4.

The average atomic mass =  (5.03 + 3(7.20) / 4

= 6.6575.
