Given Chemical Formula of the Acetone = CH₃COCH₃

Mass of the C = 12 g.

Mass of the H = 1 g.

Mass of the O = 16 g.

Molecular mass is the sum of the masses of the elements present in 1 molecule of the compounds.

Molecular mass of the Acetone = 12 + 1 × 3 + 12 + 16 + 12 + 1 × 3

= 12 + 3 + 12 + 16 + 12 + 3

= 36 + 6 + 16

= 58 g/mole.

Hence, the molar mass of the acetone is 58 g/mole.

Molecular Mass

The mass of a given molecule is its molecular mass (m), which is expressed in daltons (Da or u).  Because they contain various isotopes of an element, multiple molecules of the same substance can have distinct molecular weights. According to IUPAC, the related quantity relative to molecular mass is a unitless comparison between the mass of a molecule and the unified atomic mass unit (also called the dalton). The molar mass is unrelated to, but distinct from, the molecular mass and relative molecular mass. The molar mass, which is stated in g/mol, is defined as the mass of a specific material divided by the amount of a substance. When addressing macroscopic issues, the molar mass is typically the most relevant figure (weigh-able).

In 1928, 47.5 g of a new element was isolated from 660 kg of the ore molybdenite. the percent by mass of this element in the ore
vitfil [10]

To take the percent by mass of this element, we use the formula:

% mass = (mass of element / mass of ore) * 100%

% mass = (47.5 g / (660 kg * 1000 g / kg)) * 100*

<span>% mass = 7.20 x 10^-3 %</span>

Does 1 gram of phosphorus react with 6 grams of iodine to form 4 grams of phosphorus triodine in P4(s)+6I2(s)=4PI3(s)
mafiozo [28]

Answer:

No

Explanation:

One mole of P₄ react with six moles of I₂ and gives 4 moles of PI₃.

When one gram phosphorus and 6 gram of  iodine react they gives 8.234 g ram of PI₃ .

Given data:

Mass of phosphorus = 1 g

Mass of iodine = 6 g

Mass of  PI₃ = ?

Solution:

Chemical equation:

P₄ + 6I₂    →  4PI₃

Number of moles of P₄:

Number of moles = Mass /molar mass

Number of mole = 1 g / 123.9 g/mol

Number of moles  = 0.01 mol

Number of moles of I₂:

Number of moles  = Mass /molar mass

Number of moles = 6 g / 253.8 g/mol

Number of moles = 0.024 mol

Now we will compare the moles of PI₃ with I₂ and P₄.

                I₂              :              PI₃

                  6              :               4

                 0.024       :             4/6×0.024 = 0.02

                  P₄            :               PI₃

                 1                :                4

                 0.01          :               4 × 0.01 = 0.04  mol

The number of moles of PI₃ produced by I₂ are less it will be limiting reactant.

Mass of PI₃ = moles × molar mass

Mass of PI₃ = 0.02 mol × 411.7 g/mol

Mass of PI₃ =  8.234 g

Answer:1:En química, el número másico o número de masa es la suma del número de protones y el número de neutrones del núcleo de un átomo. Se simboliza con la letra A (el uso de esta letra proviene de alemán Atomgewicht, que quiere decir peso atómico, aunque sean conceptos distintos que no deben confundirse).
