Imagine we have <span>mass of solvent 1kg (1000g)
According to that: </span>
= 4.8 mole * 98 g/mole = 470g
m(H2SO4) which is =<span>470g
</span><span>m(solution) = m(H2SO4) + m(solvent) = 470 + 1000 = 1470 g
d(solution) = m(solution) / V(solution) =>
=> 1.249 g/mL = 1470 g / V(solution) =></span>

Answer:
Salicylic acids are clear white needle shaped crystal in room temperature and are used in pharmaceutical industries to produce analgesic.
Explanation:
- Salicylic acids are aromatic organic compound also known as monohydroxybenzoic acid which is lipophilic in nature.
- the physical properties are :
- they are colorlesss and odourless at room temperature.
- boiling point is 211°C and melting point is 315°C
- they are poorly soluble in water
- its saturated solution has pH of 2.4
- the chemical properties are:
- acytylation of hydroxy group in salicylic acid gives acytylsalicylic acid which is used as aspirin.
There are 22.5 grams of protein in one cup of soup that has 140 kcal with 8 g of carbohydrate and 2 g of fat.
<h3>What is the mass of a substance?</h3>
The mass of a substance is the quantity of the substance that is being measured in grams or kilograms.
To determine the energy from the 8g of carbohydrate, we have:
= 8g × 4 kcal/g (the corresponding calories of food type)
= 32 kcal
The energy from 2g of fat = 2g × 9 kcal/g
= 18 kcal
The energy from protein is calculated as:
= 140 kcal - 32 kcal - 18 kcal
= 90 kcal
The required mass of the protein in grams is:
= 22.5 grams
Therefore, we can conclude that there are 22.5 grams of protein in one cup of soup.
